Cloud Shortened Session, Brief Jupiter Observing

Posted: 26 March 2016

Open: Friday, 25 March 2016, 1816 MST
Temperature: 84°F
Session: 941
Conditions: Mostly clear

With a clear sky forecast and just a few clouds low in the western sky I began this session with the hopes of doing some Deep Sky Object (DSO) imaging before the waning gibbous Moon rose. Synced the observatory clock to WWV.

1826 MST: StarLock OFF. Viewed Jupiter, 102X. No moons were visible yet (bright blue sky). Seeing was surprisingly good. 1834 MST: one moon (Ganymede) visible. 1837 MST: Io and Europa now visible. (Callisto was in eclipse behind the planet.) 1840 MST: Jupiter was easily seen in the sky with the naked eye. 1841 MST: the star Sirius was now visible to the naked eye high in the south. 1842 MST: sunset.

1900 MST: began preparing the D7200 DSLR for DSO imaging. 1909 MST: finished the preparations and then saw that clouds had snuck in. The sky overhead was filled with clouds. 1914 MST: more clouds coming in. Now in much of the sky. Gave up for this session.
