              ------------- ACTIVITY LOG --------------
 Observing Specialist:  R.McMillan
 Good seeing, but thin to medium clouds all night.  We were mostly
 able to work through the clouds.  When it was too thick for the
 second-half observer to work, I did some drop-in observations on a
 brighter target; I listed that at midnight for simplicity.  Later
 the clouds thinned somewhat but still posed a little difficulty for
 observations.
