(* means a trouble report has been issued or appended to)
The telescope was opened at 18:45.  Tia Hoyes assisted with
observations the first half of the night.
In my opinion, based on the work that was completed over night, the
telescope can be used for science observations.  An engineering report
has been distributed to site staff.  Others wishing a copy can obtain
one from me.  Briefly, here are the tasks and tests that were done:
collimation - adjusted; good on axis; off axis (guide camera) shows
elongation in out of focus images
calibration lamps - tested new lamp control.  Contact the site for
information on how to access lamp control.
guide camera - new instrument block; tested guiding loop on 12.8 mag
star in twilight (works well).
pointing - new pointing model; ran blind pointing test average
pointing error was 6.2 arcsec, max was 15.2 arcsec, min was 0.4
arcsec.
tracking - one tracking test, 300 second exp at altitude of 75
degrees.  No detectable trailing, fwhm was 1.6 arcsec.
