MDM Observatory 1.3m Telescope Observing Report for 2022 Mar 31

Observer(s): Qiong Li
Institution(s): UMICH

Instrument: Nellie

Worked for 6 hours (first half of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Clear, Winds Calm
   Mid: Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

We lost the pointing at the beginning of the night observation. The telescope position ('MDM1.3m Control panel') is not same as the target's position. I tested another target, and it still has RA_OFFSET~1m18s, DEC_OFFSET~7'0''. 
Then I point the telescope to the zenith, without tracking and enter:
zero ra=(LST) dec=31:57:12 equinox=2022
It still doesn't work. Finally, I found the value for tilt sensor motion cannot change when I move the hand paddle. It is always at [-491,+458] at zenith. Next, I tried the offset (in the telescope control panel). The value for motion still didn't change. We close the dome at 12:00 am LST.
