MDM Observatory 2.4m Telescope Observing Report for 2017 Oct 10 Observer(s): John Thorstensen + Justin Rupert Institution(s): Dartmouth & MDM Instrument: Modspec+echelle Worked for 11 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 1 arcsec, Clear, Winds Light & Variable Mid: Seeing 1 arcsec, Clear, Winds Light & Variable End: Seeing 1 arcsec, Clear, Winds Light & Variable Observing Summary: Excellent night with good seeing. Devoted the last part of the night to getting a spectrum of a bright gamma ray burst counterpart while simultaneously getting images with the 1.3m. You can read all about these efforts (orchestrated by unindicted co-conspirator Jules Halpern) at https://gcn.gsfc.nasa.gov/gcn3/21987.gcn3 . The new TCS is performing well. The dome went home tonight, and the problem with intermittently unresponsive paddle directional buttons may have been a bit better, though it hasn't gone away entirely. ------------------------------ Submitted on 2017 Oct 11 [6:41:00]
