"Seeing good, transparency good. Many tall plants protruding into the sky, partially blocking light domes. Milky Way easily seen but few details, surprisingly dark, shadow of the Tucson Mountains undoubtedly helps shield lights from Tucson. Tucson light dome extends throughout the whole sky nevertheless, with Phoenix fairly large and bright to the northwest. Tucson light dome seems redder in color than Phoenix. West is pretty dark, zodiacal light strong with Venus after end of twilight. Easy to navigate on the trail after dark, some direct glare from Avra Valley, lots of air traffic. ZLM 6.5 late. SQM 1st 20.70, 2nd 20.95, 3rd 21.03."
