The sky eventually clouded over and we closed at 20:40, due to the clouds. I observed for PU02, with SPIcam, and Michael Strauss and Xiaohui Fan observed for PU04 with DIS. No problems to report. Eric Deutsch fixed a bug in the current incarnation of the guider monitor. All of his software is now running locally at APO. 2nd half observing specialist: McMillan Second half was mostly cloudy, and the telescope was closed much of the time. We were open from 22:10 to 00:50, obtaining a few useful DIS spectra but no good infrared data, and from 03:45 to 04:50, which was mostly fruitless due to GRIM's sensitivity to clouds.
