Gloria The telescope was opened at 20:00 MDT. Lew Hobbs observed with the Echelle for the first half of the night. The pointing was only about 5 arcsec off, even at high elevation. The pointing at NA2 continues to be about 30 arcsec off. Lew's run went well. 2nd half observing specialist: K. Gloria Scott Austin was on with DIS after the echelle. He lost some time because the pointing was way off on one of his fields. Other than that, his run went well. I observed for PU03 at the end of the night. I took a set of data, but unfortunately he wind had shifted by this time, degrading the seeing to 1.7 arcsec.
