                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 A damp night with some clouds first half and some high winds toward
 dawn.  Seeing was generally poor.  For most of second half, the
 humidity was technically over the limit.  But I checked surfaces in
 the dome and everything seemed high except during the period of
 highest humidity, when I closed.
 There were a few motion errors during checkout slews; I couldn't
 figure out what had caused them but they cleared up and didn't
 repeat.  The first half observer also had some connectivity problems
 which caused occasional confusion but didn't really cost any time
 since TUI and DISICC handled the disconnections smoothly.
