WIYNLost about 10mins around 21:00 when the telescope drives tripped, see MSR#27300 for details. Lost another 5mins at 02:00 when the guider gui crashed. Restarting the IPS fixed the problem. Lost another 5mins waiting for the rotator to unwrap around 03:00. Still a productive night thought! Seeing Range: 0.6-2+ arcsec, Median: 0.8 arcsec.
2.1 MeterA good night of observing with no issues.
FeedNot Scheduled
0.9 MeterNo technical issues, a decent night of observing. Seeing around 0.9 arcsec.

CommentsAnother clear and calm night!
