The Darkest Skies
in Virginia

"Sky quality measurements were recorded at Bodie Island in Cape Hatteras NS on 11/14/2007. The site demonstrated a scientific darkness reading of 21.76 SQM."

"North end of ASIS looks directly north at Ocean City on nearby Fenwick Island. Carnival in progress is very bright"

"Very dry air with some moderate winds provided visibility of 50-75+ miles during the day. At night the horizon is almost completely illuminated by cities, small towns and rural farms and ranches. Some very bright direct glare sources in the cities of Harrisonburg and Fishersville (Hospital?). The Milky Way was visible to the horizon in the SW and obscured at about 25 degrees above horizon in the NE. Very good detail in Cygnus near the zenith. Washington D.C. light dome easily visible to the ENE."

"Site 300 meters south of Big Meadows gas pump and Wayside café, seeing good, transparency good, but windy and getting hazier. Light dome from Washington D.C. brightest, many smaller ones around the horizon. Milky Way easy to see especially brightest parts in Cygnus and Cassiopeia. As night progresses, however, haziness increases and contrast decreases, especially along the southwestern horizon. SQM 21.27. Glare from several lights at Wayside and visitor center very distracting, kills night vision, illuminates landscape, much brighter than Venus from this location. By 4th set low clouds move in from the northwest and very hazy and windy."

"Color seen in light domes, mixture of sodium lights and white light. At zenith, however, Milky Way in Cygnus well defined, with great rift and little rift both seen. Bortle 4 based on zenith and ZLM, definitely 5 otherwise. Good transparency helps. Sky is definitely milky, not dark, contrast is diminished all the way to zenith. SQM 21.12 early, 21.25 late."

"Site on pullout of Skyline Drive, south sky pretty well blocked by hillside. Seeing good, transparency excellent. Bright light domes from D.C. and Front Royal dominate the north and northeast, but zenith is remarkably dark, revealing the brighter parts of the Milky Way easily. Gradient from horizon to zenith however. Milky Way invisible in dim areas like Monoceros and Gemini. Airglow appears brighter than normal because of high gradient from zenith, even toward the west where there are no bright light domes. Lots of bright glare from Front Royal, Winchester, core of D.C. light dome very bright, damages night vision, 20 degrees wide. SQM 21.33 late. NELM measured by Duriscoe but with spectacles, no contacts, in fatigued state, in Triangulum."

"FWHM definitely affected, probably by vibrations of the observation tower itself. Light polltion sources visible both in foreground and at horizon. A thin layer of haze evident to east, possibly part of approaching clouds. First data set virtually cloud free. Sky free of contrails. Limiting magnitude found in Pegasus. Andromeda galaxy visible, M15 requires much effort. Milky Way detail easily detectable near zenith. Sky appeared noticeably brighter than previous nights, possibly due to some airglow. I also think it may have to do with the atmospheric clarity. All other nights contained some amount of possible light absorbing clouds."

"This was a very clear night. High humidity. Trees covered all of horizon from this site, but light scatter was evident to the north and west especially. LZM found in Pegasus."

"Setup camera on the west side of the pond on USFWS Refuge adjoining the park. Many local glare sources visible from the visitor center and administrative offices, as well as the visitor parking lot. We were able to turn off several closer lights on the pavilion and its adjoining grass parking area. A cold night with very clear skies after a cold front moved through. The Milky Way was visible from 25° above the horizon in the north to 20° above horizon in the south. Not too much detail but M31 (Andromeda Galaxy) was visible to the naked eye and overall this night sky provides good opportunities for public observing."

The light dome from the greaer Washington D.C. area on over to Baltimore extended about 30° above the horizon. Norfolk Virginia was visible to about 20° above the horizon and Salisbury and Ocean City were easily visible to the east. The lights of Cambridge and Easton illuminated a few remaining clouds to the NNE."
