NM03 was performed with Grim. The skies eventually cleared and DIMM was started. Cirrus from about 21:00 on. 2nd half observing specialist: Loomis We had cirrus most of the 2nd half of the night. Don York observed for UC03, with the Echelle. The MC hung twice, near the beginning of his run. Both hangs appear to have been related to use of the Echelle slit viewer control panel in Remark. We had some intermittent image motion (of a few arcsec), similar to what has been reported in previous logs this month.
