AOTF was mounted but not used because of cloudy conditions. The DIMM has a new dew shield, but will require some modifications before use. The DIMM was not started because of the clouds. Although the clouds thinned out somewhat, no AOTF observations were done due to heavy cirrus. 2nd half observing specialist: Loomis Don York was the observer for UC03. The telescope was opened at 23:45 and closed at 00:15. I had time to focus the echelle, but that's all. The telescope was closed for the rest of the night.
