MDM Observatory 2.4m Telescope Observing Report for 2024 Jul 09 Observer(s): Anderson Institution(s): MDM Instrument: OSMOS Worked for 7 hours (most of the night) Conditions were Mixed most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Rain from 20:00 until 21:00. Beg: Seeing 2 arcsec, Patchy Clouds, Winds Light & Variable, rain Mid: Seeing 1.8 arcsec, Clear, Winds Moderate End: Seeing 1.6 arcsec, Clear, Winds Light & Variable Observing Summary: Observed targets for Shu. Night started out iffy with threatening clouds and a bit of precipitation closing me down for an hour. Then went fine until about 2:45am when the RA seemed to jump about 1 arcsecond after tracking for a while. I tried to continually do the same target and monitor it, and it seems to not be a creep but an actual jump the causes me to lose guiding. ------------------------------ Submitted on 2024 Jul 10 [5:13:40]
