MDM Trouble Report for 2012 Mar 14

Telescope: 1.3m
Observer(s): Skowron (OSU)
Instrument: CCDS

Problem(s) Encountered:
I had a minor problem with the paddle in TCS, similar to the problems encountered earlier. I didn't loose much time on this though.
N/S motions worked not consistently. Most of the night it was good, but on 2 objects it was hard to move the telescope in N/S direction using software paddle. 
When this situation happens, I have to put >20 arcsec in the paddle window to see the motion of the telescope. The motion I see then is of order of ~5 arcsec or so, so smaller than specified. If I put lower number than ~20 then most of the time I do not see any motion.

When this happens, it makes putting object on the slit a little more time consuming, because I have to try some more random jumps in hope that I will move the telescope were I want. This is not very problematic, thus not urgent, but I wanted to make a note on the issue.

Second thing I have noticed is that the rubber pipe attached to LN2 tank has a little hole to it (close to the place where metal pipe is attached). Leakage is not big, but it can probably grow over time.
