                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    Weather clear at time of opening, but high humidity. Jeff Morgan from
UW showed up to work with SPIcam on scattered light tests. All went well
except for some frost on the IRSC window.
    For the scattered light tests we needed to track Jupiter again, and a
quick call to Nancy Chanover at NMSU helped out since she calculated all
the rates for her run 2 days ago. Once we had correct tracking rates all
went well, until the clouds moved in.
    Humidity rose and temp dropped and we had to close at 23:10 due to
possibility of a frosty mirror.
 Observing Specialist, 2nd Shift: Russet McMillan
 The humidity bounced around at borderline conditions for a few hours,
 very frustrating since the telescope was colder than the air.  At
 last the dewpoint went down and we re-opened at 02:10.  Widespread
 thin cirrus around midnight gradually decreased to nothing by
 twilight.
 We tracked Jupiter almost down to the lower altitude limit, then
 switched to Arcturus as a poor substitute.  While Jeff was working
 with SPIcam, I did some tests with the guider, persevering in spite
 of very good seeing when I really wanted fatter images.  A comparison
 of focus between SPIcam and the guider at low airmass showed good
 agreement, but the guider was severely undersampled at the time.
 Even when I changed the binning, a few images of  1u
 per 0.1 cubic feet.
                             TELESCOPE STATUS

 Telescope drives operational. Current Remark version: 2.62. Current
 guide software version: GIm Ctrlv3.0b27. Current TCC version is 2.4.1
 Current MC version: v1_7_3.
