                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 Dust prevented us from opening during the first part of the evening.  The
 dust levels finally dropped to acceptable levels around 19:00 and I
 opened and then focused the telescope to try to get some Lens data.
 Unfortunately, but not unexpected, the seeing was >1.5 arc sec and I
 turned the time back over to D. York for use with the Echelle.
 Humidity dew point depression reached closure levels around 21:25 and I
 let Don finish up the remaining couple of minutes on his exposure and
 then closed the building.
 2nd Half Observing Specialist: R.McMillan
 Second half alternated between high humidity and high winds.
