Open: Sunday, 24 January 2016, 2029 MST Temperature: 44°F

Session: 911 Conditions: Mostly clear

Upon opening the observatory I discovered that the observatory clock backup battery had failed, causing the clock date/time to be incorrect as a result of a recent widespread power outage (caused by our US Bureau of Indian Affairs electric utility company). I resynced the clock to WWV using the observatory shortwave radio.

2041 MST: viewed the star Sirius, 83X and 222X, in an attempt to see Sirius B (the "Pup Star"). No success this night.

Next, viewed the one-day past Full Moon, 83X. Set up for afocal imaging with the iPhone 6s Plus using the SteadyPix Universal Smartphone Telescope Photo Mount. This is the Moon, afocal 77X:

Added the 2X PowerMate for this afocal image, 154X, along the terminator:

I removed the iPhone and afocal adapter and did some lunar observing at 222X. Nice views.

2109 MST: final look at the Moon, 83X.

Close: Sunday, 24 January 2016, 2117 MST Temperature: 42°F
