              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tspec is good.  I did not take darks.
Frost accumulated on the secondary mirror at the beginning of the night.  The mirror covers for the primary remained shut but the primary may also have accrued frost. While it was clear tonight after 19:00, we did not open on account of the effects from the blizzard which ended this morning.
