Observing Status

| WIYN | Lost 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. |
