MDM Observatory 2.4m Telescope Observing Report for 2019 Sep 05 Observer(s): John Thorstensen Institution(s): Dartmouth Instrument: OSMOS/B Worked for 7 hours (off and on through the night) Conditions were Mixed most of the night. No equipment or software problems were encountered. Seeing and Weather: Clouds from start until midn.. Beg: Overcast, Winds Light & Variable Mid: Seeing 1+ arcsec, Patchy Clouds, Winds Light & Variable End: Seeing 1+ arcsec, Patchy Clouds, Winds Light & Variable Observing Summary: Cloudy for a while at first, then cleared for a bit around 9, then cloudy again until after 11 -- one of those nights. But the second half was almost all usable, though never entirely clear. I didn't see any clear examples of the telescope jumping despite tracking for several hours. There's some likelihood that it's fixed, though with something this intermittent one errs on the side of caution. ------------------------------ Submitted on 2019 Sep 6 [6:09:30]
