The ice and crusty snow has not melted from the enclosure roof and the humidity was high most of the evening. The enclosure was pointed into the sun during the day with the roof heaters running, but the it was too cold for any melting to occur. Charles Corson checked the enclosure roof at the end of the day to find no change. Austin Tomaney (UW12) called in to check on the status of the telescope, and was informed of the current situation. Alberto Noriega-Crespo was shut out also.
