0010 UT Trying to wake MODS, but it hands during 'blue tedpower on' 0020 UT Attempting to reset MODS to clear the problem w/ 'tedpower' 0030 UT Test preset to TCS 0058 UT mods1b.20130412.0003-5 have a large artifact at the blue ends of the spectra due to light leaks from solar illumination inside enclosure 0158 UT Sunset. Opening telescope and beginning pointing check. 0202 UT Resetting GCS due to MODS in calibration mode. 0206 UT Difficulty acquiring 4-th magnitude pointing check star. 0214 UT Finished first pointing check. Moving to fainter star to check focus 0216 UT Moving to pointing star near first object (Feige 34) 0220 UT Unable to focus on pointing star. Sky bkg too high? 0229 UT Moving to acquire Feige 34 0234 UT Lost guide star. May be attempting to observe through cloud cover 0238 UT "Parter CALIBRATION timeout" Refresh MODS controller. 0252 UT Slewing to SN 2012aw field 0400 UT Slewing to SN 2007rt field. Unable to maintain guiding 0412 UT Slewing to SN 2005bf field. Unable to locate guide star. Clouds 0455 UT Taking spectrum at SN 2005bf, but through clouds. Data will be poor 0550 UT Taking additional spectra to make up for the limited signal in the first two spectra 0628 UT Moving telescop to Bootes field to begin EAGES_487588 0647 UT Removed recommended rotation adjustment due to slight offsets between reference stars. This did not appear to help. 0653 UT Re-sending the preset command due to collimation error by AGw. Failure. Appears to have resulted from pupil crossing lenslets. 0657 UT Sending AGw to on-axis position w/ bright star to check collimation 0710 UT Sending telescope to SN 2012au field. Unable to acquire guide star. 0730 UT Attempting to acquire SN 2012au 0748 UT Beginning observations of SN 2012au through variable clouds. Guide star magnitude highly variable. 0750 UT Lost running log entry due to wiki error. Attempting to recover from separate file, but some log entries will be absent. 0844 UT Sending telescope to HZ 44 field to take spectrophotometric standard 0849 UT Beginning standard star spectra 0907 UT Moving telescope to SN 2010mc reference object & beginning acquisition. 0910 UT IIF Error. Trying to send a manual preset to a nearby star. 0912 UT Failed to begin guiding for nearby star. 0920 UT Resetting GCS to attempt to clear the problem. 0924 UT GCS working again. Collimating telescope & returning to SN 2010mc. 0939 UT Beginning spectra of SN 2010mc 1000 UT Sky is essentially clear with only light cirrus. 1047 UT Slewing to Bootes field for EAGES_487588. 1105 UT Beginning spectra of EAGES_487588 1107 UT Position of guide star pupil image jumped again, but collimation appears to be okay so far. 1150 UT Finished second integration for EAGES_487588. Postponing additional integrations due to encroaching twilight. Beginning calibrations 1200 UT Conducting spectral flats & arc lamp calibration 1257 UT Finished MOS & longslit flats and some of the slitless flats. Unable to finish all calibrations prior to handover. David Atlee -- 2013 April 12
