MDM Trouble Report for 2017 Jun 02

Telescope: 2.4m
Observer(s): Simonian (OSU)
Instrument: ModSpec/Echelle

Problem(s) Encountered:
When I attempted to move the guide probe to a different star in 
the JSkyCalc Guide Star Selector, I would click a new star on
the screen, select  Move Guide Probe , and confirm  Yes  that I 
want to move the guide probe. No errors are reported, and the 
MIS reports the status of the guider movement. However, when I 
look at the guider screen which is constantly updating under 
the  Expose  tab, I don't see any change in the field.

It's entirely possible that this is a user error and I'm
forgetting to enable an option. However, I remember 
successfully being able to move the guide probe yesterday when I
needed a new guiding field. The fact that it didn't work this 
time was puzzling, but not particularly urgent. For 5 minute 
exposure times, it was perfectly reasonable to just maintain 
the object on the slit once in a while. But if this is an 
intermittent problem, I wanted to document it.
