                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night started out with poor seeing and widespread cirrus.  During
 first half the clouds gradually thickened until the observer admitted
 he wasn't getting any science at all.  I considered closing, but as
 there was no real threat from the weather, I used the time for still
 more echelle slitviewer characterization instead.  When it cleared
 up, I handed the telescope back over to the observer.  During second
 half, it remained clear and the seeing dropped to around an
 arcsecond, so the observer was able to get plenty of science done.
