MDM Trouble Report for 2024 Jul 09

Telescope: 2.4m
Observer(s): Anderson (MDM)
Instrument: OSMOS

Problem(s) Encountered:
RA jump towards the end of the night. Not sure timing has much to
do with it as I was using the same exposure length of 600 secs
most of the night. This RA jump was repeatable and happened 
three straight times as I was testing it to see if it was a
creep or a jump. RA was holding steady and then all of a sudden
I would lose guiding and see the RA jumped by an arcsecond. To
ascertain tracking again, I needed to use the paddle to go west. 
Hopefully this is not indicative of a bigger issue since the 
encoder was just replaced. This may have happened last night as
well, but since clouds were present I may have assumed that is
what caused the guider to lose the star.
