Blackrock Summit
Shenendoah NP
"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."
Big Meadows
Shenandoah NP
"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."
