MDM Trouble Report for 2019 Sep 03

Telescope: 2.4m
Observer(s): John Thorstensen (Dartmouth)
Instrument: OSMOS/B

Problem(s) Encountered:
About a dozen times tonight, rather intermittently but perhaps 
more often in the north, the telescope would jump eastward and 
kick the guide star just out of the box, maybe 10-15 arcsec.  

Pushing the east guide
button for a few seconds brought it back in, but it meant I had
to pay more attention than usual to the tracking!
