              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Heavy clouds before sunset thinned enough that we could try some
observations, but then high winds and approaching precipitation
forced us to close.  When the precipitation failed to arrive and the
wind dropped, the clouds persisted.  I was able to get some
observations with the echelle on a very bright target, but the clouds
were more trouble in the infrared so the second half observer
struggled, and some of the time while we were open no useful photons
were collected.
