SYNOPSIS FOR NIGHT: =================== We never opened again (sigh). GENERAL COMMENTS (see Problems below for details): ================================================== A stream of moist air gave us about an inch of snow. Clouds, humidity, fog, and snow were with us all night long. On the plus side, we have no hardware or software problems to report. The site air system behaved itself all night long. endNight -doTpm was run. The spectrograph 180-l dewar will need swapping out early in the day.
