                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 The APO days staff did an amazing job of putting the telescope back
 together.  Many of tubes of super glue in the dumpster and you can
 barely tell the primary was at once in a million pieces, not a scratch
 on it!
 I started cooling the enclosure around 16:45 with the cooling fans and
 opening the enclosure itself (under light cirrus skies).  I had the
 instrument checked out and ready for the observers to start their
 darks/biases with SPIcam by 18:10.
 Other than pesky clouds everything ran smooth tonight.
