Observing Specialist: N.C.Hastings
     The telescope was delayed in opening due to dust counts of over
20,000 at times. We did finally open at 22:40. The power had failed
today for about 2-3 hours but all seems in good working order. The
automatic power switch to the utility building performed properly.
     At 01:10 I moved the tertiary to the NA1 port but found that the
tip and tilt values did not change from NA2. I stopped and restarted
the collimate process twice and made two slews. Nothing seemed to
help. When I restarted the collimate process I kept getting NOSUCHQUE
replies. I had to restart the telrun process and the mcnode and it
still took 2 slews before I saw the correct values for A, B and C
using 'tert status' in the TCC window. After this was straightened out
all worked smoothly...

used is north=0 degrees, east=90 degrees. The dust count is for the
particles > 1 micron per 0.1 cu.ft.
