                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Wind, dust, high humidity, and clouds kept us closed all night.
 It's springtime in the Desert Southwest.
 Jon B. worked on getting the data from our new anomometer working
 tonight.  Unfortunately where it is mounted on the Ops building roof is
 not a good location for it (blocked by the trees too much).  Elana
 reported winds over 35-50MPH and the new anomometer was only reporting
 maybe 18-20 winds or less.  This wasn't too suprising since the wind was
 coming out of the west and we have a lot of trees blocking us from that
 direction.  Even the Sloan enclosure was reporting speeds up to 40 MPH
 (with the enclosure closed).  We normally don't see much from that with
 the building closed.
