Mica View
Saguaro NP
Local Relevance
For observers in Green Valley, Mica View serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Seeing very good transparency very good. ZLM 6.3 in evening, 6.7 by early morning, Milky Way in Canis Major barely seen. Bortle 6 based on everything but ZLM. Upon dark adaptation very easy to walk the trail, cross country travel possible with some difficulty, getting close to saguaros reveals their green color when viewed opposite Tucson. No part of the sky is dark, the entire western half washed out with a milky glow, bright parts of the Tucson glow reddish in color, but a bluish hue to the south (AFB?). Tanque Verde ridge illuminated, shows 3D character, especially in evening. SQM 1st set 20.20, 2nd 20.43, fifth 20.63."

"Lights from Tucson obvios to the west, the glow extending well towards the zenith. M31 is a medium averted vision object (located in light dome). The sky is noticeably darker to the east. The winter milky way is faintly visible. City glow casts faint shadows at this spot. Some detail on the mountains can be seen. Some lights from nearby development. A very cold night for Tucson. Air traffic and headlights coming out of Reddington Pass may also be present in pictures."
