Brookhaven.

"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."

"Site at summit, on flagstone floor behind rock wall. Seeing good transparency excellent, very windy, gusts to 25 mph. Sky bright all around, due west may be only area free of light domes, otherwise there are many bright light domes and glare from unshielded lights in towns, especially Luray and Stanley to northwest and southwest. Sky glow gradient from horizon to zenith, dome of Washington D.C. area to 50 degrees altitude, Harrisonburg to 30 degrees. 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."
