Last Summit Night

Tonight looked promising. The sunset was awesome and humidity was dropping. It did end up being a good night, but I didn't see any of it. There was snow and ice on the dome and we had to test the dome. When we opened the dome shutter nothing happened, but when we closed it a bunch of little ice chunks came in with the snow. Totaly unsafe. If the primary mirror had not been covered, it would have been damaged. That's no way to go observing. Another canceled night....
