              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
New DIS Slitmasks and repositioned the boresight better for the new masks.
Clouds disapated enough around 2:30 that we might be able to do the high altitude tracking tests.  Definately not photometric and a lot of high cirrus.
When I tried to change the secondary focus, after changing instruments to Agile, I got a CorrPos error.
I called Russet and she homed the secodary.
High alt tracking tests
(I collected most of this data, N,S,E, last month.  see 20150306)

West_horz  ~65         (on Dataq plot)

Dust climbed over the closure limits around 04:30.
A nice lunar eclipse at the end of the night.
