MDM Trouble Report for 2013 Jul 14

Telescope: 1.3m
Observer(s): Sarah Schmidt (Ohio State University)
Instrument: Nellie (imaging)

Problem(s) Encountered:
1. The telescope would nod and jitter during exposures. The 
problem seems relatively unpredictable. Estimate about 0.75 
hours of time lost based on the number of bad images. I think 
this is a relatively well-known problems, but examples are:
/home/data/direct/Jul15.0015.fit
/home/data/direct/Jul15.0049.fit
the issue was most persistent at high dec (+84), but I also had 
it at a dec of +20. 

2. The guide software occasionally freezes (4x in the night), 
displaying a strange image and greying out all buttons except 
disconnect. I can quickly solve the problem by disconnecting 
and reconnecting (so no time lost) but I didn't encounter the 
problem before.
