                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd shift: Noel Camron Hastings
     We opened at 19:30 for cooling under partly cloudy skies. The
second half observer took sky flats with SPIcam while the first half
observer took cals with the echelle. We focused to bad seeing and all
ran well.
     The APO web server had to be rebooted at 23:15 when it was found to
be unresponsive. The reboot fixed the problem.
     Noticed that the Echelle cannot point much to much better than 5-8
arcseconds accuracy. I think a new pointing model could help this, as
well as determining if the tertiary is behaving differently at the NA1
port. Pointing seems to be reasonably good at NA2 still.
     Clouds came in thick for a half hour and then cleared up, which was
the only weather time we lost.
