Observing Status
| 4 Meter | No technical problems. Seeing measured between 1.6 and 1.8 arcsecs on Mosaic, but it was difficult to get a good focus tonight because clouds interrupted every attempt at a focus sequence. |
|---|
| WIYN | Five instances of Hydra failing to pick up a button. Details in WIYN nightlog. Otherwise no problem aside from the clouds. Seeing estimated between 1 and 1.5 arcsec based on the fops. |
