                ------------- ACTIVITY LOG --------------
Observing Specialists: R.McMillan
Nice clear night, but variable seeing.  The numbers in the focus log
are a minimum; seeing was over 2 arcseconds at times.
The telescope and instruments generally behaved well.  There were
some elongated images during a very high northern transit with
NIC-FPS, but windshake probably contributed to this.  There were also
some larger-than usual magnesensor errors from azimuth (in the range
15-25 arcsec), so the drive might want to be cleaned or adjusted.
