PLAN
----
Continue running load JAN2207A.  Do an ascending CTI measurement, then
obsid 7564, an ACIS-S ToO observation of the Gamma Ray Burst 061121 to
search for the X-ray jet break time. Then do obsid 6408, an ACIS-I
observation of NGC 1893 to study the initial mass function of this
star forming region in the outer part of our Galaxy.
No Comm this shift.

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Nine supports over the weekend. No issues. Three segments of JAN2207A
were uplinked, on-board loads are good until 026:03:45.
JAN2907 products expected out tomorrow.
Some network migration was performed last Saturday -- no impacts.

Quick look data:
OBSID   Target           Time                        Comment
-----   ------           --------------              -------
Quick looks 7636, 8122, 8212 look ok.  Cal observation 8396 of Mkn 421
looks ok. Cal observations 8356 through 8360 of Capella look ok. They
show the known HRC "tail" to the image. 8358 and 8359 show a streak
while slewing to the source -- an HRC hot pixel (?) does not show the
streak.
