                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: B.Ketzeback
 First half went well. The observer was looking at a region of sky where
 not many guide stars could be found but otherwise things went smoothly.
 2nd Half Observing Specialist: R.McMillan
 The second half observer got started a little late because there was
 no advance email sent and the observer logged in just in time
 (rather than a little early).  We had light cirrus and mostly bad
 seeing, sometimes making it very difficult for the guider to
 recognize guide stars.  Aside from the seeing-related difficulties,
 everything worked perfectly.
