              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tspec is behaving, took 1000 darks.
I found multiple crushed moths on the az drive but the alt drive was very clean.  I cleaned both.  To fill GIFs, I turned the valve about 1/6 rotation, then turned it off, then cracked it open about 1/10 rotation.  It took nearly 30 min to fill.  In the morning, it took only about 10min.
Night started clear and I opened the dome at 18:34.  Daylight saving went into effect today so one hour was added to the listed bright time. The night stayed clear with moderate seeing in the beginning and improving towards midnight.
