More strange Lights above Brown Mountain Dec 13, 2014

Once again, our BMl Cam 1 camera overlooking Brown Mountain has captured a MedEvac helicopter flying north over the mountain, landing at the Caldwell Memorial Hospital in Lenoir, and then taking off 30 minutes later and flying back south over the mountain.

In this 4-minute sequence, the helicopter is inbound (right-to-left) with it's bright landing light burning. 


The helicopter leaves the heliport at the Caldwell Memorial Hospital in downtown Lenoir 30 minutes later with it's bright landing light burning, but soon turns it off. 
Notice the fainter blinking navigation lights as the helicopter flies south (left-to-right) over Brown Mountain.
 
Once again, BML Cam 1 has captured unusual and unexpected yet normal manmade lights over Brown Mountain.  Actually such MedEvac helicopter flights have been captured by the camera several times this year (see previous post).

Strange Lights above Brown Mountain July 4-5, 2014

Low-flying MedEvac helicopters have been seen flying at night above Brown Mountain on several occassions this year.  On the night of July 4, 2014, one was captured landing and then taking off by our BML Cam1.  The helicopter flew south-to-north (right-to-left) above Brown Mountain landing at the Caldwell Memorial Hospital in Lenoir at 11:38 pm on the 4th.  The helicopter left Lenoir approximately 36 minutes later at 12:14 am on the morning of the 5th and flew southward (left-to-right) over Brown Mountain.  For those wondering---yes there is a Heliport at the Caldwell Hospital in downtown Lenoir.



Such low-flying aircraft above Brown Mountain demostrate that unexpected manmade lights do occassionally occur in the area and can lead to misidentifications by uninformed or unprepared observers.

Forest Service Rd 4099 Staged Light Test Apr 9, 2014

A member of our BML research team conducted an unannounced staged light test on the night of April 9, 2014.  His motorcycle lights on Forest Service Rd 4099 along Little Chestnut Mtn Ridge were captured by our BML Cam1 during his out and back round trip.  In addition, Mike's 135-lumen headlight was also visible as he hiked the short trail to the summit of Wildcat Knob.  The following image is a composite stack of 15 separate 30-second time-exposure images taken by BML Cam1 during Mike's ride and hike.  Although the team was not aware of Mike's planned light test, as soon as we saw that night's online video, we correctly guessed that the lights were produced by a motorcycle on road 4099.  This unannounced light test helped establish the actual path of FS Rd 4099 and showed the team's quickly growing expertise in understanding lights observed in the area.


Chestnut Mtn Staged Light Test Nov 4, 2013

This image is a stacked composite of 3 seperate time-exposure images of our Nov 4, 2013 staged light test on Forest Service Rd 198.  Brown Mountain itself lies just beyond the right edge of the image.  The lights are approximately 2.3 miles east of the camera, which was set up at the  Brown Mountain Overlook on NC Hwy 181.  Althought normally gated, FS Rd 198 is temporarily opened during the fall hunting season every year giving hunters and our BML Research Team access to the area of Chestnut Mtn.  As planned, the road was driven on the night of Nov 4, 2013 by one of our team members while I manned the camera.  Such distant lights are occasionally seen and misinterpreted as mysterious BMLs by uninformed and unprepared observers at the Hwy 181 Overlook.  Light tests like this one help demostrate that unexpected manmade lights do occur in the area and that they can be impossible to distinguish from non-manmade lights by most observers.

31 Lights on Brown Mountain 16Aug14

A probable ATV rider was captured traveling south on Trail # 2 on Brown Mountain on the night of August 16, 2014.  Although leaves were still on the trees at the time, the light was readily visible at many points along the trail.  This is one of the maintained ATV Trails as part of the US Forest Service Brown Mountain Off-Highway Vehicle Recreation Area (34 miles of trails atop Brown Mountain).  The image was created by stacking 31 seperate 30-second time exposure images taken by our BML Cam1.  The trace of the lights matches the convoluted path of ATV Trail # 2 as shown on the Forest Service map of the recreation area.  The lights in this image also closely match my lights as I hiked the same trail on December 11, 2014 (see earlier post).  The compiled image below shows 36 minutes as the probable ATV traveled south on the trail and 21 minutes as the ATV sat at Bear Rocks with it's headlight pointed toward BML Cam1. 

July 4th Fireworks over Brown Mountain

This composite image clearly shows July 4th sky-rocket fireworks in the valley east of Brown Mountain.  The fireworks were captured by our BMl Cam1 which sits atop a house on Jonas Ridge and looks southeast toward Brown Mountain.  The image was compiled by stacking 4 seperate 30-second time exposure images together.  A MedEvac helicopter on it's way to the Caldwell Memorial Hospital in downtown Lenoir was also captured, first withfaint navigation lights on, then with it's bright landing light burning.

12 Lights on Pinch-In Trail in Linville Gorge August 13, 2014

This time-lapse photo shows 12 staged hiker lights on the Pinch-In Trail on the west side of Linville Gorge.  The lights were captured by our BML Cam2 camera which sits at a house near the lower end of the gorge.  BML Research Team members Dr. Cato Holler, Chris Holler, & I hiked the trail with 520- and 320-lumen handheld spotlights.  Recent forest fires have created open vistas along the middle portion of the trail where our lights are visible, while dense trees blocked our lights on the upper- and-lower-most parts of the trail.

Dangerously Low Flying Airplane over Brown Mountain 11Dec14

During my staged light test hike on Brown Mountain on the night of December 11, 2014, I was shocked to witness a dangerously low-flying twin-engine airplane only about 100 feet off the ground!


Low-Flying Airpalne over Brown Mountain on Dec 11, 2014

It's not easy to get to Lael's Rock (my name)---I had to bushwhack about 20 minutes from Trail #2
through very dense brush on a steep rocky slope to reach the site of what I suspect is Ralph Lael's 1962 encounter with mysterious lights that he interpreted to be aliens.  The large bare rock exposure is clearly visible in the daytime and on moon-lit nights when the monlight reflects off the wet rocks.  Just 3 minutes after I arrived at the rock, and just moments before the end of twilight, a very loud twin-engine airplane about 100 feet off the ground flew overhead!  The plane actually came over the top of BM and stayed at the same 100 feet or so elevation above the ground as it descended into Holly Springs valley, then banked hard to the north as it followed Upper Creek east of Ripshin Ridge.  The plane did not have sufficient altidute to clear Ripshin Ridge so it was forced to make that sharp left turn.

Why the airplane was flying so dangerously low just moments before total darkness is unknown.  Had I not been on Lael's Rock at the exact moment the plane flew overhead and witnessed the event, we would have been hard pressed to explain the light streak.  And had Cam1 not have been purposefully started about 45 minutes early that evening in order to capture my light before nightfall, Cam1 would not have captured the lights of the airplane in the first place---in other words, we almost missed this strang light!  In the 2 years Cam1 has been operating, we've never seem such a low-flying plane.  Just goes to show that strange manmade lights do occur unexpectedly on BM!!

16 Lights on Brown Mountain Dec 11, 2014

The night of December 11, 2014 was cold and clear----perfect for a night hike and some staged light tests on Brown Mountain!  I hit the trail about dark, visited several known bare rock exposures with open views toward our BML Cam1, and hiked a 4-mile loop atop the mountain.  My light was a 520-lumen re-chargeable handheld spotlight that I've used on previous light tests.  The following image is a composite stack of 16 individual 30-second time exposure images taken at various times during the 4.5 hour hike by Cam1, which lies atop a house on Jonas Ridge 7 miles west of Brown Mountain.  This is the same image, with the same field of view, seen in all Cam1 images this year; i.e., the camera has not changed position all year.

16 Lights on Brown Mountain December 11, 2014


520-lumen rechargeable handheld spotlight used for Dec 11, 2014 Light Tests
 
Light from my handheld spotlight was captured at 16 different places on Brown Mountain by BML Cam1---these are the 16 spots of light on the mountain visible on the composite time-exposure image above.  With the leaves now off the trees, I was able to see the distant Jonas Ridge House lights where Cam1 is located at numerous places along the various trails I hiked that night.  Sure enough, Cam1 caught my spotlight at many places along the trails.  During the same hike back in August when the leaves were still on the trees, my light was only visible at Bear Rocks and along FS Rd 4099 with open views toward Cam1.  The birght lights at Lael's Rock and Bear Rocks seen in the image above are the same 520-lumen spotlight pointed directly toward Cam1 for a full 30-second time exposure.

Measured Line-of-Sight Azimuths for BML Cam1 (Jonas Ridge Camera)

An intergal part of our BML research is acurately locating specific lights seen on our various camera images.  Knowing exactly what is visible in an image of distant objects is critical in determining exactly what a specific light might be.  Our BML Cam1 is located atop a house on Jonas Ridge and has been running intermittently since February 2013.  It is pointed southeast toward Brown Mountain, which lies 7 miles away.  While the camera's field of view was manually changed a few times last year, it remained constant during 2014, except for some minor high-wind shaking.  The following image shows 11 seperate very-acurate line-of-sight azimuths that allow us to better understand the location of lights that are visible within the camera's field of view.  Distortion of the image due to the curvature of the camera lens is obvious from the unequal increments of degrees horizontally across the image.

Accurately measured line-of-sight azimuths in degrees
for BML Cam1 (Jonas Ridge)

Note that these lines of sights include prominent geographic landmarks, fortuitous Moon rises, airports/heliports where lighted aircraft were photographed landing or taking off, and our own staged light tests at known sites on Brown Mountain.  Various software programs were used to measure the azimuths correctly.  The majority of the lights beyond Brown Mountain are those of Lenoir and some of the communities immediately south of town.  However some tall communication tower lights of Statesville are visible on the far horizon near the middle of the image.  Only the northern-most 1/4 of Brown Mountain itself is visible within the camera's field of view and the city of Hickory is out of view far to the south (right).

BML Cam1 Jonas Ridge Camera for November 2014

The Brown Mountain Lights Research Team's BML Cam1 sits atop a house on Jonas Ridge and overlooks Brown Mountain 7 miles to the east.  It has been running intermittedntly since February 2013.

Dr. Dan Caton, Professor and Director of Observatories, Dept. of Physics and Astronomy, Appalachian State University (Boone, NC) installed and operates the camera as part of an on-going research project. Dr. Caton also installed and operates another research camera (BML Cam2) located at the southern end of Linville Gorge.  The images from both cameras are compiled into nightly videos and posted on YouTube---just search "Brown Mountain Lights Camera 1" (or Camera 2) for the individual nightly videos.  Both cameras are modified digital meteor-hunting cameras.

To date, numerous lights have been recorded by Cam1, including: town/city/rural lights in the valleys beyond Brown Mountain, fireworks, communication tower lights, airplanes and helicopters, highway-vehicle lights, off-highway-vehicle lights, stadium lights, back-country user lights, and brush/forest fires.  Natural lights captured by the camera include stars, Jupiter, Mars, Venus, Mercury, the Moon, meteors, lightning and fireflies.  Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 300 hours of nocturnal observation time on 29 seperate nights during November 2014, resulting in 33,666 individual 30-second time-exposure images.  This brings the totals over the past 22 months since start up in Feb 2013 to 3,654 hours of nocturnal observation time on 410 seperate nights resulting in 397,374 individual time-exposure images.  Each of these images has been examined in detail by members of our research team.

No abnormal, unusual or unexpected nocturnal lights were recorded by BML Cam1 during November 2014.   However, the usual distant city/town/rural lights, airplane lights, and light from the bright planets Jupiter and Mercury were visible this month.  Possible Leonid meteors were visible on Nov 7 & 9; while Moon rises on Nov 17, 18 & 19 produced promined lens flares and over-saturated Moon lights.  Rainy/foggy weather obscured views a few nights, especially the last week of the month.  Reflections of Hwy 181 vehicle lights on the east side of Ripshin Ridge were ocassionally visible.   Smoke stack plumes & clouds in the valley s. of Lenoir were also visible a few nights.

The following images are selected to show some significant features visible during November 2014.  Note that the camera position does not change during this sequence of images.  Blurry or out-of-focus distant lights are caused by movemnt of the lights as well as rising heat currents that distort the incoming light waves during the time exposures.

BML Cam1 Jonas Ridge Camera for October 2014

The Brown Mountain Lights Research Team's BML Cam1 sits atop a house on Jonas Ridge and overlooks Brown Mountain 7 miles to the east. It has been running intermittently since February 2013.


Dr. Dan Caton, Professor and Director of Observatories, Dept. of Physics and Astronomy, Appalachian State University (Boone, NC) installed and operates the camera as part of an on-going research project. Dr. Caton also installed and operates another research camera (BML Cam2) located at the southern end of Linville Gorge. The images from both cameras are compiled into nightly videos and posted on YouTube---just search "Brown Mountain Lights Camera 1" (or Camera 2) for the individual nightly videos. Both cameras are modified highly light-sensitive meteor-hunting cameras.

To date, numerous lights have been recorded by Cam1, including: town/city/rural lights in the valleys beyond Brown Mountain, fireworks, communication tower lights, airplanes and helicopters, highway-vehicle lights, off-highway-vehicle lights, stadium lights, and back-country user lights. Natural lights captured by the camera include stars, Jupiter, Mars, Venus, the Moon, lightning and fireflies. Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 306 hours of nocturnal observation time on 31 seperate nights during October 2014, resulting in 34,250 individual 30-second time-exposure images and 3,400 individual 10-second time-exposure images. This brings the totals over the past 21 months since start up in Feb 2013 to 3,354 hours of nocturnal observation time on 381 seperate nights resulting in 363,708 individual time-exposure images.

No abnormal, unusual or unexpected nocturnal lights were recorded by BML Cam1 during October 2014.  However, the usual distant city/town/rural lights, airplane lights, and light from the bright planet Jupiter were visible this month. Rainy/foggy weather obscured views a few nights and reflections of Hwy 181 vehicle lights on the east side of Ripshin Ridge were ocassionally visible. Dust plumes & clouds in the valley s. of Lenoir were also visible a few nights. Multiple airplanes landing & taking off from Statesville airport were visible many nights.  Special 10-second time exposures were recorded on Oct 25/26, but produced no new revelations.  Faint moving ATV lights were visible on the ridgeline near Bear Rocks on BM on Oct 30.  Stationary, occassional camper lights at campsite near Bear Rocks were visible on the nights of Oct 30 & 31.

BML Cam1 Jonas Ridge Camera for September 2014

The Brown Mountain Lights Research Team's BML Cam1 sits atop a house on Jonas Ridge and overlooks Brown Mountain 7 miles to the east. It has been running intermittently since February 2013.

Dr. Dan Caton, Professor and Director of Observatories, Dept. of Physics and Astronomy, Appalachian State University (Boone, NC) installed and operates the camera as part of an on-going research project. Dr. Caton also installed and operates another research camera (BML Cam2) located at the southern end of Linville Gorge. The images from both cameras are compiled into nightly videos and posted on YouTube---just search "Brown Mountain Lights Camera 1" (or Camera 2) for the individual nightly videos. Both cameras are modified highly light-sensitive comet-hunting cameras.

To date, numerous lights have been recorded by Cam1, including: town/city/rural lights in the valleys beyond Brown Mountain, fireworks, communication tower lights, airplanes and helicopters, highway-vehicle lights, off-highway-vehicle lights, stadium lights, and back-country user lights. Natural lights captured by the camera include stars, Jupiter, Mars, Venus, the Moon, lightning and fireflies. Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 271 hours of nocturnal observation time on 30 nights during September 2014, resulting in 31,296 individual 30-second time-exposure images. This brings the totals over the past 20 months since start up in Feb 2013 to 3,047 hours of nocturnal observation time on 350 different nights resulting in 326,058 individual time-exposure images.

No abnormal, unusual or unexpected nocturnal lights were recorded by BML Cam1 during September 2014.  However, the usual distant city/town/rural lights & airplane lights were visible this month.  Rainy/foggy weather obscured views much of the month.  Reflections of Hwy 181 vehicle lights on the east side of Ripshin Ridge were visible many nights in the low clouds/fog.   Dust plumes & clouds in the valley s. of Lenoir were visible many nights.  Multiple airplanes landing & taking off from Statesville airport were visible on Sep 7 (11:56 pm--2:16 am) & again on Sep 21-22 [including bright runway lights turned on at 3:46 am (6:30 video time), plane lands at 3:53 am (6:37 video time), then runway lights off at 4:06 am (6:50 video time)].  Lights from CMC-North East Stadium in Kannapolis were burning from the start of the video at 9:27 pm until 10:05 pm (0:00-0:38 video time) on Sep 13.

BML Cam1 Jonas Ridge Camera for August 2014

The Brown Mountain Lights Research Team's BML Cam1 sits atop a house on Jonas Ridge and overlooks Brown Mountain 7 miles to the east. It has been running intermittently since February 2013.
 
Dr. Dan Caton, Professor and Director of Observatories, Dept. of Physics and Astronomy, Appalachian State University (Boone, NC) installed and operates the camera as part of an on-going research project. Dr. Caton also installed and operates another research camera (BML Cam2) located at the southern end of Linville Gorge.

Natural lights captured by the camera include stars, Jupiter, Mars, Venus, the moon, lightning and fireflies. Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 256 hours of nocturnal observation time on 30 nights during August 2014, resulting in 30,738 individual 30-second time-exposure images. This brings the totals over the past 19 months since start up in Feb 2013 to 2,776 hours of nocturnal observation time on 320 different nights resulting in 294,762 individual time-exposure images.

No abnormal, unusual or unexpected nocturnal lights were positively identified by BML Cam1 during August 2014.  While observation during much of the month was hampered by stormy weather (clouds, rain & fog), a staged light test by myself on August 20th was instrumental in proving once again that normal back-country user lights are readily visible at Bear Rocks on the summit of Brown Mountain (6.7 miles east of the camera) and on FS Road 4099 (5.6 miles distant from the camera).   Non-staged ATV headlights were visible on the nights of Aug 16th (southbound on Trail #2) and Aug 23rd (northbound on trails along the ridgeline of Brown Mountain).  Other than the lights mentioned above, the usual distant manmade lights (urban/rural, airplanes, etc) were visible most nights above Brown Mountain throughout the month.

Staged Light Test Aug 13-14, 2014 Pinchin Trail BML Cam2

Staged Light Test Aug 13-14, 2014  Pinchin Trail  BML Cam2

Three Brown Mountain Light Research Team members hiked down the Pinchin Trail on the west side of Linville Gorge before dark on the evening of August 13/14, 2014 and conducted staged light tests on the hike back up the trail to the car after dark.  The hikers were Dr. Cato Holler, Jr., Chris Holler, and myself.  Hiker lights included 520- and 320-lumen handheld spotlights and headlamps up to 78 lumen.

These staged tests establishes the easy visibility of the type of handheld lights commonly carried by back country hikers and also establishes exactly where that trail is located in the camera's field of view.  The tests confirm our earlier suspicions of similar lights seen on previous dates when unknown hikers and campers were on the trail.  A forest fire in 2006 destroyed most of the vegetation along the trail, allowing for nearly-continuous open views, especially on the middle portions of the very steep trail.  During the hike, I recorded the times of our arrival and departure at specific landmarks along the trail---these matched perfectly with lights recorded by the video on BML Cam2. The full video can be seen at: https://www.youtube.com/watch?v=1TOgK4CMJqI  see video time (0:35-1:00) for our hiker lights and (1:20-1:27) for our headlights on Dogback Mtn.

Our BML Cam2 is located at a house south of the southern end of Linville Gorge. It is operated by Dr. Dan Caton, Lee Hawkins, and Annette Farah of the Dept. of Physics and Astronomy, Appalachian State Univ., Boone, NC. The camera is located 4.5 miles south of the Pinchin Trail and has been running intermittently since October 2013.

Our vehicle's headlights and 2 handheld spotlights are pointed southward toward the camera. 
Headlights of vehicles on this gravel raod are often visible at this open viewspot.

Once again, staged light tests like this strongly suggests that differentiating between distant nocturnal manmade lights and non-manmade lights is extremely difficult if not actually impossible for uninformed observers relying only on visual clues.

Staged Light Test July 14, 2014 Wolf Pit Trail BML Cam2

My solo nighttime roundtrip hike to the summit of Shortoff Mtn on the Wolf Pit Trail on the evening of Monday July 14, 2014 provided a staged light test that establishes the high visibility of the type of handheld lights commonly carried by back country hikers. Both my 520-lumen handheld spotlight and my 4-LED 78-lumen headlamp were visible to the camera. The exercise also establishes exactly where that trail is located in the camera's field of view and confirms our earlier suspicions of similar lights seen on previous dates. An extensive forest fire in 2007 destroyed most of the vegetation along the trail, allowing for nearly-continuous open views, especially on the upper portions of the mountain. On the trail, a party of 4 hikers without lights were encountered after sunset but before darkness, while overnight campers were seen near the summit, just out of view of Cam2. My recorded time notes for my arrival at specific landmarks matched perfectly with lights recorded by the video. The full video can be seen at: https://www.youtube.com/watch?v=bGC4l74Ibus

Our BML Cam2 is located at a house south of the southern end of Linville Gorge. It is operated by Dr. Dan Caton, Lee Hawkins, and Annette Farah of the Dept. of Physics and Astronomy, Appalachian State Univ., Boone, NC. The camera is located 2.5-3.0 miles from the Wolf Pit Trail and has been running intermittently since October 2013.

To date, numerous lights have been recorded by Cam1, including: town/city/rural lights in the valleys beyond Brown Mountain, fireworks, communication tower lights, airplanes and helicopters, highway-vehicle lights, off-highway vehicle lights, stadium lights, and back-country user lights. Natural lights captured by the camera include stars, Jupiter, Mars, Venus, the moon, lightning and fireflies.  Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 147 hours of nocturnal observation time on 20 nights during July 2014, resulting in 16,546 individual 30-second time-exposure images. This brings the totals over the past 18 months since start up in Feb 2013 to 2,335 hours of nocturnal observation time on 263 different nights resulting in 279,106 individual time-exposure images.

The following images are selected to show some significant features. Note that the camera position does not change during this sequence of images. Blurry or out-of-focus distant lights are caused by rising heat currents that distort the incoming light waves during the time exposures---lights that instantly flash on and off once produce sharp images.

Both cameras are modified highly light-sensitive comet-hunting cameras.

To date, numerous lights have been recorded by Cam1, including: town/city/rural lights in the valleys beyond Brown Mountain, communication tower lights, airplanes and helicopters, highway-vehicle lights, off-highway vehicle lights, stadium lights, and back-country user lights. Natural lights captured by the camera include bright stars, Jupiter, Mars, Venus, the moon and lightning. Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 184 hours of nocturnal observation time on 27 nights during June 2014, resulting in 20,930 individual 30-second time-exposure images. This brings the totals over the past 17 months since start up in Feb 2013 to 2,372 hours of nocturnal observation time on 243 different nights resulting in 283,490 individual time-exposure images.

The following images are selected to show some significant features. Note that the camera position does not change during this sequence of images. Blurry or out-of-focus distant lights are caused by rising heat currents that distort the incoming light waves during the time exposures---lights that instantly flash on and off once produce sharp images.

BML Cam1 Jonas Ridge Camera for May 2014

The Brown Mountain Lights Research Team's BML Cam1 sits atop a house on Jonas Ridge and overlooks Brown Mountain 7 miles to the east. It has been running intermittently since February 2013.

Dr. Dan Caton, Professor and Director of Observatories, Dept. of Physics and Astronomy, Appalachian State University (Boone, NC) installed and operates the camera as part of an on-going research project. Dr. Caton also installed and operates another research camera (BML Cam2) located at the southern end of Linville Gorge. The images from both cameras are compiled into nightly videos and posted on YouTube---just search "Brown Mountain Lights Camera 1" (or Camera 2) for the individual nightly videos. Both cameras are modified highly light-sensitive comet-hunting cameras.

Natural lights captured by the camera include bright stars, Jupiter, Mars, Venus, the moon and lightning. Disappointingly, Cam1 has yet to record any support for mysterious or unknown lights in the Brown Mountain area.

BML Cam1 recorded 172 hours of nocturnal observation time on 24 nights during May 2014, resulting in 19,846 individual 30-second time-exposure images. This brings the totals over the past 16 months since start up in Feb 2013 to 2,188 hours of nocturnal observation time on 243 different nights resulting in 262,560 individual time-exposure images.

The following images are selected to show some significant features. Note that the camera position does not change during this sequence of images. Blurry or out-of-focus distant lights are caused by rising heat currents that distort the incoming light waves during the time exposures---lights that instantly flash on and off once produce sharp images.

Image transition errors produced the band of faint lights across the lower portion of the image.
These are an exact but dim duplicate of the bright band of electric lights above Brown Mountain.
The dim vertical lines that connect the dim lights with their parent bright lights are 'smear lines' produced during the fly-in transition between the previous 30-second-exposure image and the next image.

Staged Light test atop Brown Mountain Aug 20, 2014

Last night, Wednesday Aug 20, 2014, I hiked trails atop Brown Mountain for yet another staged light test.  My 520-lumen handheld spotlight and my 78-lumen 4-LED headlamp were both visible to our research camera on Jonas Ridge (BML Cam1).

I drove to Chestnut Gap, bicycled FS Road 4099 the three miles to the north end of Brown Mountain, and then hiked to the prominently exposed Bear Rocks via the connector trail & ATV Trails 2, 8, 1B & 6; arriving at 10:24 pm.  In the first image above, my 520-lumen spotlight can be seen at the extreme right edge of the camera's field of view---6.7 miles from the camera.
 
Upon leaving Bear Rocks at 10:38 pm, I followed ATV Trail #2 back to the north end of Brown Mountain and arrived at my vehicle at 1:09 am.  On the way, I stopped along FS Rd 4099 at several clear views and shined my 78-lumen headlight toward BML Cam1, however only one such spot (at 5.6 miles from the camera) appeared within the field of view of the camera (see extreme left side of image below).

Such staged light tests help establish actual landmarks and the visibility of manmade lights commonly carried by back-country travelers.
