              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The telescope was not usable tonight because of adjustments being made for the visiting instrument.  We would not normally account this as EQUIP time, but it's hard to justify listing it as OBS.  Weather was cloudy for most of the night due to Hurricane Kay; it might have been borderline usable during second half, but I decided that listing the time under bad weather made the most sense.
