MDM Trouble Report for 2012 Dec 17

Telescope: 2.4m
Observer(s): Haojing Yan & Zhiyuan Ma (University of Missouri-Columbia)
Instrument: OSMOS + B4K

Problem(s) Encountered:
MDM24MWS1 has problem with its /data directory - it seems that
some external hard drives intended to be mounted under this
directory were not properly mounted. A simple task like  ls /data 
will just hang there forever. However, an external disk properly
mounted under /data as a subdirectory can still be directly
accessed, for example,  cd /data/hiltner  will get into this
directory and show everything all right.

We spent a lot of time to focus in order to get round star
images. This included tuning  colfocus and camfocus . As for most
of the time the ambient temperature dropped to well below 15 C,
the camfocus value had to go up to > 6300um to get the right focus.
This is not necessary a  trouble  that needs to show up in this
 trouble report , however this might a piece of useful information
that worth of being recorded somewhere.
