1st half: None.
2nd half: various. Within first 30min = OCS interlock error, resolved with "Configure" button; lost primary air. As we started the series of 20s and 40s exposures, we noticed that the tracking was bad in RA (thought it was guiding initially, but it is tracking). Guider showed swings of +-2" in some images, and +-1" in MANY images. Tried different slew/settle strategies, but this tracking problem unfortunately affected the majority of images. NEED HELP if possible to find soln to tracking problems in East at -45 deg. Perhaps recheck balance?

High cirrus clouds through some of the night, although seeing was typically below 1.0 arcseconds for most of the first half of the night.
Ran DES "obstac" for whole half of night without incident
