MDM Trouble Report for 2001 Feb 15

Telescope: 2.4m
Observer(s): Jacob Noel-Storr (Columbia)
Instrument: CCDS

Problem(s) Encountered:
THE MIRROR COVERS did not open (I closed them while I closed the 
dome to do some dome flats, then when I tried to re-open them 
only one side opened*... The instrument rotator was not at zero 
either - I left it where it was so as not to rotate it with 
the still closed cover). -> Should the rotator always be set 
back to zero before closing the covers? I looked at the manual
but it only says 'dont rotate it with the covers closed'...

*[This, at least, is when I noticed this problem, but with 
hindsight I do not remember checking that all the covers 
had opened at the start of the night, I may have only looked 
at the near side in the exitement of the humidity finally 
dropping.]

I did not solve this problem. (I tried opening the covers a
few times, but always the same thing).
