              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Lame sauce.  We had clouds all night and Jupiter waved in an out, never really enough to get more than half a data cube. However, there was an issue with the instrument itself that was causing internal reflections and we used the time to address the issue and it was fixed! Hooray!  Turns out the instrument was slightly tilted with regard to the incoming light and just needed a slight correction.  We do not have a place scale for NIAC so I do not have a focus value to report so we estimated seeing off Sloan which was 1".
The dome camera froze and I was unable/unaware of how to fix the problem so it's still stuck.
