The telescope was opened at 21:15.  Prior to this, Jon Davis, Mark Klaene,
Karen Gloria, Bruce Gillespie, and myself were all on site working on the
telescope axis problem.  The motor for the altitude drive was replaced, and
the amplifier was replaced.  It seemed that something may have burnt out.
After several hours, we finally got on the sky, and Rene Walterbos, Rich Rand,
Neb Duric and Joe Collins were all on site to use spicam for imaging and
driftscanning.  The pointing was much better than it has been in the past few
days.
At 01:45, WSMR took over using the time for a mission.  The time for PU01
and NM07 was traded to WSMR.
I checked the temps. for DIS, and they were stable all evening.
