Hi Sam-

Interesting to compare our observations - last night I was on Gates Pass to get 
to darker location and I never saw it naked eye.  Tonight I watched from our 
front yard in Midtown Tucson and after spotting it in binoculars, was able to 
pick it out naked eye - weird!  My wife Melinda, with the recently bionic eyes 
didn't need binoculars  to locate it naked eye, picking it right out - she saw 
it last night too from the Pass...

A photo from this evening's viewing. I went out west of Tucson to get a cleaner 
horizon. There definitely was more muck in the sky compared to yesterday. As a 
result, I was not able to pick this up naked eye this evening. A bit of a 
bummer because the setting was so much nicer than what I saw the previous 
evening. Glad to hear that others had more ideal viewing conditions. I agree 
with Brent that tomorrow evening should be very nice with the crescent Moon. I 
hope some of the dust and other muck moves on for a more pristine western 
horizon.
