              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Agile failed at checkout; unwedged the AGILE timer card to fix it.
UW06 handed over a few minutes early.
We had varying amounts of clouds all night that we were able to observe through, but no other weather problems. We closed up at 06:16 when the clouds+twilight combined to make it too difficult to observe any more, and switched over to cals for the rest of twilight.
Temperatures around 0C all night, humidity ranged between 30 and 40%.
