Gloria The telescope was opened at 18:00 MDT. Zlatan Tsvetanov and Wei Zheng observed remotely with DIS, doing SDSS follow up observations. There were no problems during their run. 2nd half observing specialist: K. Gloria Dara Norman and Gene Magnier observed remotely with SPIcam. They had a good, photometric night, but lost a half hour at the end due to a TCC process dying, which caused the telescope to stop tracking. I got this sorted out, but by that time it was the beginning of astro twilight, so they decided to start taking flats.
