                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We started out with some NIC-FPS work to see if changing the reset
 voltages could reduce image persistence from saturated stars.  Later
 we mounted FastCam2, Daughter of FastCam, and I got tons of data
 with it during second half.  Craig also did lots of work with the
 guider software during the evening, sometimes in parallel with work
 on other instruments, sometimes superseding the other work.
 Skies were mostly clear, seeing was moderate to excellent, and
 everything worked well except the things we were messing around with
 anyway.  The guider software has been left in a partly-usable state,
 with strangely familiar bugs; it may have been regressed back to the
 wrong version.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
     Note: The Tower Dust counter appears to be down at this time
