                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
Fritz debugged some more drive problems at the start of the night then I got onto doing a couple
of pointing models.  Russet looked at the model and said she liked it but not much change from the
currently implemented one (so I did not implement it).  Separate email with model was sent
distributed.
I then started the tracking tests (E, S, N, and W)
South_long (alt up, Az left)
North_long (alt down, Az right)
I might have had the wrong RA for the North tracking tests.  At 30 mins into the run I noticed we
were already past transit by 10 degrees which didn't seem right and it was already.  I aborted the
run at frame 41 and restarted (this time I went LST +15 mins since I was running out of time).
2nd run is called north2.  I will let this one run about 15 mins or so thru transit (about 30 mins
data instead of 90).  I aborted at frame 49 due to twilight.
I ran out of time to get the west tracking test done.
