              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Thick-ish clouds thinned somewhat a few hours into first half, so we
opened and got a few spectra, but then heavy overcast blanketed us.  The
satellite said the clouds were orographic.  They finally started to clear
when it was too late for the second half observer to get anything useful.
Agile was not used on-sky, but did behave perfectly for the cals.
