              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Things started off windy and at the beginning of the night we had a collision when a strong gust from the east hit as I was slewing from park.  It was a hard hit and took me over 20min to move the telescope off the crash sensor.  Once we got on sky we saw that we weren’t missing much.  The seeing was nearly 5” and refused to drop until midnight hen arctic came on.
It got rather nippy tonight and when I checked on Apollo the SBIG values were 0.  I crawled under the telescope to turn on the laser and wake up the pump and then everything was good.
