MDM Observatory 2.4m Telescope Observer's Report for 2006 Oct 21 Observer(s): Prieto & Watson Institution(s): OSU Instrument: CCDS and Retrocam Worked for 12 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 Calm Mid: Seeing 0.8 arcsec, Clear, Winds Calm End: Seeing 1.3 arcsec, Clear, Winds Calm Observing Summary: The weather was great the whole night. Interestingly, the CCDS readout pattern seems to have disappeared after Bob changed to the 50g/mm grating and then stayed that way after we changed back to the 150g/mm grating on 10/20. Hopefully it stays that way! ------------------------------ Submitted on 2006 Oct 22 [6:17:48]
