              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
CU time was split between the two programs, as agreed by the users.  They shared today and tomorrow, so it evens out between them. Between the two nights, CU05 observed tonight and CU06 will get tomorrow.
We started out with heavy hlouds and high humidity, with some small snow flurries.  These all cleared up by 23:00, and we were able to open for a productive night.
Dcam shutter was sticking from the start, with 1 or 5 seconds exposures.  Did not hinder observing.
