MDM Observatory 2.4m Telescope Observing Report for 2015 Feb 24 Observer(s): Stephanie Douglas, Jose Zorrilla Institution(s): Columbia University Instrument: ModSpec/Echelle Worked for 9.5 hours (all night) Conditions were Non-Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Cirrus, Winds Light & Variable Mid: Cirrus, Winds Light & Variable End: Cirrus, Winds Light & Variable Observing Summary: We opened at sunset and everything went smoothly for most of the night. The transparency was pretty poor though. Around UT~10, the guide probe x-axis stopped responding. I quit the GUI, power-cycled the MIS, and restarted the GUI as suggested by the response to a previous trouble report. ------------------------------ Submitted on 2015 Feb 25 [5:42:16]
