Buckhorn Group Camp
Black Butte Lake RA
"Site on a knoll just northwest of the group camp, excellent monitoring site with easy access. Seeing excellent, transparency poor. Lingering smoke and haze from wildfire, humid. Despite high extinction, an excellent sky near the zenith, with the dark lane in the Cygnus star cloud visible. Northeast through south along the horizon has numerous bright light domes, the brightest of which definitely affects dark adaptation. Early evening sky is much brighter overhead than late, presumably because of outdoor lights being shut off, but airglow decrease also a factor. By early morning, the light domes are seen to extend to less than 45 degrees above the horizon, while in early evening to at least 60 degrees, with only a small area near the zenith lacking a distinct brightness gradient. SQM 21.44 at 9:30 PM (Sales), 21.77 (Duriscoe) 12:30 AM LMT."
