"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."
