              ------------- ACTIVITY LOG --------------
 Observing Specialist:  R.McMillan
 Clear or mostly-clear skies all night, with poor seeing first half
 and better seeing second half.
 We lost a little time when the echelle slitviewer crashed and
 neither I nor the remote observer noticed promptly, so a half-hour
 exposure turned out to be unusable.  A second crash was caught more
 quickly and resolved with no loss of observing time.
