                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: C. Hastings
 Sky was clear at sunset, but humidity started to ramp up as sun set
 forcing me to close. I was about to turn over time to next program
 for cals when the humidity suddenly dropped again! I marched upstairs
 to open again when....
 Upon starting flats I found a failure with the azimuth. The problem
 was traced to an electronics unit in the azimuth controller. I tested
 some components on the unit in question and discovered a bad fuse,
 replaced it and we were back online, with excellent seeing!
 All else ran smoothly until shift change.
 2nd Half Observing Specialist: J. Dembicky
 There was a problem with the Alt location not being recognized, which
 prevented the 2nd'ry from moving for SPIcam,  after the instrument
 switch.  I killed the drives and then re-initialized them along with a
 test slew from the TCC and Remark.  That seemed to clear the problem.  I
 focused SPIcam for the 2nd half observers then to make sure everything
 was working properly and get them on their way.  No PR was submitted
 since it seemed to be a interim problem that fixed itself after
 re-initialization of the drives.
 Everything rans smoothly tonight and we also saw a very nice meteor
 shower here at APO to boot!
