Problem Reports

6614	10:01-10:09	00:08	Dome did not move to correct azimuth for trajectory, but dome azimuth appeared correct in TCS
5832	09:57-09:57	00:00	HEFI GUI likely disappeared after finishing stack measurement
6581	13:00-13:00	00:00	Dome stuck at NEAR_CLOSED while closing at EON.	Dome would initially not open again, so I moved the dome azimuth ~20 degrees, stopped it, and was able to start the dome opening again. I attempted to close the dome fully after re-opening it slightly, but the dome shutter still stopped at NEAR_CLOSED. I left it in that state.

TO Comments	Partly cloudy and breezy night with stable temperature.
