PLAN
----
Continue running load MAY3104C. Finish obsid 5327, an HRC-I DDT
observation of the moon.  Then do obsid 4770, an ACIS-S/HETG
observation of the Circinus Galaxy to study reflection X-rays from the
central black hole, and to monitor Ultraluminous X-ray binaries.
No comm this shift.

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the last 24 hours.  No issues. One load segment
was uplinked; on-board loads good until 157:05:15.
FOT/MP had encountered problems with next week's schedule. Products
are expected out later today with a load review at a time to be
announced, possibly not until tomorrow.
Two CAP's were executed yesterday. CAP 919 successfully patched the
CPE to increase the momentum unload threshold and deadband to 31.9
and 10.0, respectively. CAP 750L was an auxiliary to that procedure to
verify the correct CPE memory contents for those quantities.
At the 1410 comm tomorrow (10:10am EDT) ACIS will run CAP 917 to
uplink their software patch.
