SYNOPSIS FOR NIGHT: =================== Never open. GENERAL COMMENTS (see Problems below for details): ================================================== Clouds at sunset. 18:00 the humidity around 90%. 20:00 the sky mostly clear, but the humidity still close to 90%. During the night sky got cloudy and the hymidity rised above 95%. 04:20 - we got a dewar presure error. We checked the nitrogen container and found out that we left the tap closed, opening the tap, brought the situation to normal. 04:40 we endNight-ed.
