MDM Trouble Report for 2024 Mar 30

Telescope: 1.3m
Observer(s): Huiyang Mao, Mingxuan Xu (Purple Mountain Observatory)
Instrument: CCDS

Problem(s) Encountered:
There seems to be something wrong with the focus, We can get two spectra while 
pointing at a point source. We found that we cannot change the center wavelength 
with the Prospero command window. The center wavelength is always 6603 Angstrom although
it shows 4950 in the header. We closed the dome because of high humidity in the second
half of the night.
