                 ------------- ACTIVITY LOG --------------
          1st Half Observing Specialist: Camron Hastings
   Off sky due to engineering work on telescope. We had a rather large
dust
event today, which I thinks signals the beginning of spring winds, and
with all the clouds tonight, we picked a good time to take things apart!
