John Holtzman and Maki Sekiguchi were on sight to observe high resolution spectroscopy. They took long integrations of up to an hour on one galaxy. Charles Corson used the slit camera and GUIDER to focus in high resolution, with the 2 arcsec steel slit. Chris Stubbs and David Reiss turned their time over to Alan Diercks and the UW01 program. There was a small amount of trouble keeping the GUIDER on a guide star during this time. Earlier in the evening, we encountered no problems to speak of.
