              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Hooray, we made it to equinox! What a boon we've had with this Worm Moon!
The long winter is behind us and we can now enjoy the solar winds of change.  It didn't get quite as windy as they predicted, barely 32mph!  We were able to open without issue but the clouds hung around nearly all of A half and annoyed us.
Seeing wasn't the greatest but hey, we had half a night of clear skies and weren't on generator power so I call that a good night! Sadly, since it was IR all night, we observed straight until the crack of dawn. I guess I'll have to wait until next week to celebrate the equinox by having 12 hours sleep.
No problems tonight.
