Observing Specialist: T.Sutherland,R.McMillan
Thanks Candace for the remote support!
Beautiful weather at the start of the night. I opened the dome at 4:00pm to start venting.
Had to reboot dataq/strip chart computer since everything froze. Got it back up and running though after a little bit of troubleshooting.
Overall it was a quiet night!
No morning IOL since echelle cals were being taken.
