MDM Observatory 1.3m Telescope Observing Report for 2011 Sep 17 Observer(s): Uthas, de Miguel Institution(s): Columbia Instrument: R4K Worked for 11 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Clear, Winds Calm Mid: Clear, Winds Calm End: Clear, Winds Calm Observing Summary: Very nice night, instrument and telescope behaved perfect (except for the problems caused by the previous thunderstorm, homing the dome, and focusing). We still have problems with the prospero command go and also mgo . We do long time-series with many exposures and occasionally, the files seems to get stuck and won't transfer into the data directory. When doing startup and runinit again, all the stuck frames do transfer at the same time, no data is lost. Error message is: warning, could not update nextfile and lastfile . Also, the upper limit of mgo 99 is really not enough for us.... ------------------------------ Submitted on 2011 Sep 18 [15:14:00]
