Comments: 

About midnight local time the humidity hit 76% and it was totally foggy so Telops closed the dome. We tried again at about 3:30 local time to open again but it was too cloudy to even do a pointing and the humidity started rising so we closed again. RASICAM was indicating almost complete cloud cover. We called it quits at 4:30am
