MDM Observatory 2.4m Telescope Observing Report for 2015 Nov 28 Observer(s): Hodges-Kluck, Jeon, Shin, Park Institution(s): Seoul National University Instrument: OSMOS/B Worked for 13 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 3 arcsec, Clear, Winds Light & Variable Mid: Seeing 2.3 arcsec, Clear, Winds Light & Variable End: Seeing 2.3 arcsec, Clear, Winds Light & Variable Observing Summary: It was a clear night. We observed all night. When we first opened the dome, the slit stopped part way up, (possibly because of activating the auto-dome before it was totally open?). When we turned the auto-dome off, we opened it and had no further problems. In the evening we lost pointing and restored it using the tilt sensors, but the E/W sensor showed 0.00 with no change until we tapped the monitor, at which point it showed the correct value. ------------------------------ Submitted on 2015 Nov 29 [7:17:02]
