MDM Observatory 2.4m Telescope Observing Report for 2019 Jun 09 Observer(s): Ryan Chornock Institution(s): Ohio University Instrument: OSMOS/B Worked for 8.5 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.75 arcsec, Patchy Clouds, Winds Light & Variable Mid: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable End: Seeing 1.5 arcsec, Overcast, Winds Light & Variable Observing Summary: Patchy clouds most of the night. The worst clouds in the first half of the night were consistently to the east, so I focused on targets in the west. I worked almost the whole night, although there were probably 2 hours of data that won't be useful due to clouds. ------------------------------ Submitted on 2019 Jun 10 [4:26:48]
