                   ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Quiet. Thin cirrus blanketed the site from late afternoon onward.  We had
a Remark crash at about 22:40 due to a badly parsed object name coming
from TUI but recovered quickly.  Seeing was good throughout most of the
half despite winds shifting from due west to SW.  Don ran a few minutes
late with permission of the second-half observer.
 2nd Half Observing Specialist: R.McMillan
 Thin cirrus continued throughout second half; any loss of throughput
 was mostly offset by the good to excellent seeing.  Everything
 worked perfectly, with the primary and motors well-behaved right up
 to the altitude limit.
