Murphy-Chambers Farm
Harpers Ferry NHP
"Set up on dirt road near canons at Murphy-Chambers Farm. Sky is cloud free at start of data collection with some low clouds along the horizon appearing later in the evening. Very nice location for night sky viewing, as this site is blocked from all direct glare sources. Milky Way is washed out in the lower sky from skyglow. Charles Town is easily visible to the west, the metro areas of Baltimore and D.C. have a light dome up to 30 degrees. For the most part, this area is surrounded by very bright skyglow along the horizon, though the natural terrain produces shielding that allows for comparatively good viewing. An SQM reading of 20.39 around midnight."
Military Meadow
Rock Creek Park
"Clear, good transparency after front moved out. Many near-field lights and cars. Andromeda glimpsed with difficulty. SQM 18.36"
