MDM Observatory 2.4m Telescope Observing Report for 2019 Jul 31 Observer(s): Clarkson, Fiolka, Boyd Institution(s): UM-Dearborn Instrument: ANDOR Worked for 5 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: High Humidity from 8pm until 10pm. Beg: Clear, Winds Calm Mid: Seeing 1 arcsec, Cirrus, Winds Calm End: Seeing 1 arcsec, Clear, Winds Calm Observing Summary: Got on-sky shortly before midnight - observable conditions despite rain earlier in the day. Clear although probably not photometric; seeing probably about an arcsec (a star 1.4 arcsec South of our science target was clearly separated from the science target throughout). We experienced power problems with the ANDOR PC. A workaround was found during the interval prior to opening, so no science time was lost.
