              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The TCC was restarted during the day which resulted in the telescope focus going to 0.  I did not consider this when I set the instrument after slewing.  This was a large move for the secondary and it failed to move.  There was then a great deal of screaming, panic, running, and calling Russet before we lost the first good sky on Mercury we've had in days.  Because Russet is God, we only lost about 20min.
We had good weather!  Finally! And we saw Mercury!  And Jupiter! and some cool super nova!  Seeing could have been better but I’m not going to complain about moderate seeing. We *totally* saw aurora on Io. Guiding was so good that we guided on an eclipsed (invisible) object. It was a good night!
