                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
Observing Specialist: Deglman
Delayed opening due to moderately thick cirrus.  Some echelle calibrations
were done during this time.  The "Net" went down for UW04 and then also
locally.*  Restarted mcnode and had Remark users reconnect.  Things were
fine after that.  Opened at 21:10 under cirrus conditions.  The echelle's
"efocus" is working once again.  UW07, using Grim, indicated the pointing
is off somewhat (apparently not as good as before Thursday's engineering
run).  Princeton (PU09) had problems connecting with Remark.*  Worked by
telephone for awhile.  Problem went away in about one hour. Uneventful
remainder of the night.  DIMM was not opened due to virtually continual
cirrus cloud cover.  Closed at 06:35.  Some Grim calibrations were done
for PU09.
