Gloria The telescope was opened at 18:45 MDT. Kevin Krisciunas was on site to observe for UW02 with SPIcam. He got three of his targets plus standards done in his brief time slot. I had to do local pointing corrections after large slews. After Kevin, Zlatan Tsvetanov was on, observing remotely with DIS. I had to correct an error in altitude after I turned the motors back on. This was an error reflected in the magnesensor position, so I think it was due to some slippage of the altitude axis rather than the pointing model. The JH06 run went well, although the seeing was a bit variable at times. 2nd half observing specialist: K. Gloria Scott Austin was on, observing remotely for WS02, with DIS. Scott graciously allowed Zlatan to run 5 minutes over into his time to finish an exposure. His run went well. The seeing was a bit mushy at times. We were at around 2 airmasses, however.
