              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Kosmos cal stage needed to be homed, but was not reporting it in the status window.  We couldn't move the cal stage and it threw an error msg in the log window, which flagged me to the problem.
Clouds got too thick to observe anything in the slitviewer by around 19:36, even though I opted to keep the dome open after this.  We decided to close the dome at 21:50 after 2 hrs of not getting any data at all due to clouds and the wind speeds outside increasing.  No sense risking the telescope by being open if we cannot get anything at all.
We gave up at 04:25 with lots of clouds and more on the way.
