                ------------- ACTIVITY LOG --------------
1st Half Observing Specialist: McMillan
	The dome was opened shortly after sunset, with partly cloudy skies and
precipitation in neighboring counties.  The precipitation never reached
us, and the humidity didn't *quite* make it to the limit before dropping
again.  Seeing was terrible throughout first half, ranging from 2-4
arcseconds, with the telescope temperature changing very rapidly so that
it was hard to keep up with the focus.
	There was some difficulty with the guider monitor on startup which
actually turned out to be a problem with the TCC logs (which are read by
the guider monitor).  Craig fixed it in timely fashion, and everything
else was normal.
2nd Half Observing Specialist
	We started the second half with GRIM II and no problems. We switched to
SPIcam at 02:35 MDT. I have returned GRIM to its original position,
leaving the cables attached to the support cord. With this configuration
we can still place the DIS dewer near the wall when operating with DIS
and we will no longer need to clip and unclip the cabling.
                   ****** OBSERVER COMMENTS ******
E.Turner (PU03): A productive night, all systems worked well.  Usual
excellent support from Russet.  Very stable and accurate pointing
allowed fast set-ups.
K.Krisciunas (UW01): A very successful half night with GRIM and SPIcam.
Observed one supernova field in H for 240 integrations. Got standard
field twice in H.  In BVRI observed two SN fields, plus four Landolt
stds fields over a range of airmass of 1.1 to 2.4 (so will have
extinctions in four filters). Also got some frames on three SDSS RR Lyr
candidates.  Seeing good high up, but understandably not so good at 3
airmasses.
