MDM Observatory 2.4m Telescope Observing Report for 2015 Sep 06 Observer(s): R. Mark Wagner Institution(s): OSU Instrument: OSMOS Worked for 2.5 hours (off and on through the night) Conditions were Overcast most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.8 arcsec, Overcast, Winds Calm Mid: Seeing 1.8 arcsec, Overcast, Winds Calm, RH 72% End: Overcast, Winds Calm Observing Summary: Thanks to Eric for coming up on Sunday and resetting the MIS and looking at the disperser indexing in OSMOS. After I reset the IE last night it seemed to work just fine. No issues tonight after going through several target acquisitions. Frustrating night with the weather. Opened ok and ran some sky flats. But by 20:10 it was overcast and bad enough to close. I reopened at 22:00 after the ok from KPNO but I was closed again by 22:30. I didn't reopen until 01:20 but by 02:00 thick clouds returned and I closed for good. KPNO closed at 02:32. Totally overcast. ------------------------------ Submitted on 2015 Sep 7 [2:56:06]
