"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."

"Exceptionally clear skies and air for this eastern US site. 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. With some lengthy dark adaptation, this observer was able to see 6.7 magnitude star in Pegasus."
