              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Overcast with radar returns nearby, high humidity and high wind all night.
2nd half UC04 observers:  Mike Solontoi, Geza Gyuk
When the weather finally allowed me to try opening at about 05:00, I cracked the dome shutters open slowly.  I heard ice crack and a little bit of snow fell into the enclosure.  None got on the mirrors, but there is a small amount near the mirror covers.  I don't want to get ice/snow on the telescope, so I will not try to open again this morning.
