Problems: 

At the end of the previous night, the DECam icon was unable to launch all the SISPI web windows and interfaces; this was fixed by Klaus, Ann and Alistair during the day, and we were all ready to go by the afternoon. Thank you! We had no major problems during the night. Minor issues: RASICAM is not working. Environmental displays on SISPI gui (dimm, wind info, etc.) are still not available. 

Comments: 

Seeing variable during the first part of the night (1-1.7"), but settled down and most of the night had ~1" seeing in the z-band; Seeing ballooned again at the end of the night, but we were also working at airmass ~ 2 .
