MDM Observatory 2.4m Telescope Observing Report for 2016 Oct 18 Observer(s): Frank Institution(s): OSU Instrument: OSMOS Worked for 13 hours (all night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1.2 arcsec, Clear, Winds Calm Mid: Seeing 1.0 arcsec, Clear, Winds Calm End: Seeing 1.2 arcsec, Clear, Winds Calm Observing Summary: Great night without any problems (except for the bright moon, which obviously cannot be fixed). One very small issue that I observed : upon the start of the session (after a runinit ), I took multiple BIAS frames. Twice, prospero in the middle of around 10 consecutive exposures, complained that the file under the given name already existed, and aborted the sequence after saving the last file under a name like 8001044K.00c.fits . I twice restarted the sequence after a runinit again, with the sequence number properly adjusted -- after that, smooth sailing and no further complaints of already existing files. ------------------------------ Submitted on 2016 Oct 19 [6:29:48]
