Observing Status
| 4 Meter | No problems. Lost about 2.5 hours to clouds that were too thick for our somewhat faint guide stars. Seeing ranged from 0.98 to 1.4 arcseconds, typically around 1.2 arcseconds. |
|---|
| WIYN | No problems. Seeing estimated from FOPs to range from 0.5 to 1 arcsecond, typically around 0.7 arcsecond. |
|---|
| 2.1 Meter | Lost about 1/2 hour to problem with telescope floating in DEC while doing a focus sequence. Had on MOP hang on another focus sequence. At the end of the night there was a socket error when trying to start an image. Observer attempted to shutdown MOP via the "File menu->exit" - MOP hung at this point. I was able to finally get it to shutdown but I think there is still a problem with it. MOP is currently shut down. Seeing ranged from 0.9 - 1.4 arcseconds, typically 1.2 arcseconds. |

| Feed | Not Scheduled |
|---|
| 0.9 Meter | No problems. Lost about 4.5 hours to clouds, Seeing was measured at 1 arcsecond (all night). |
|---|
| Comments | Seeing was pretty stable but clouds did hamper observing. It may have depended on where you were
pointing. |
