Plan: - Running JAN1600c load. Doing OBSID  319 NORMAL GALAXIES,
ACIS-S, no grating.

9 AM meeting report
-------------------

There is a TOO, the Vela pulsar, which had a sudden change in spin
rate, interpreted as a starquake, on Jan. 16, as seen in radio. We
hope to uplink the TOO load at the next pass, 5-8 pm tonight. The
observation would be done tomorrow, with the maneuver starting at
019:23:18. The work on the load is going well, and Kevin is hoping to
produce products by about noon. Darrell reports that there were 3
supports, and 4 dumps, and we uplinked a portion of the current
load. We had a data problem with the IDR, losing 42,500 VCDUs. We are
trying to recover that data, which got to the ground but didn't get to
us. We are evaluating proposed changes to protocol that would verify
receipt of the SSR dump before resetting the pointers. Ken reports the
next regular load is being impacted by the TOO, but projects no
serious problem. The OFLS Rel. 8 is in test, ready to generate command
loads. We asked when the continuous dither patch will be uplinked -
the answer is awaited.

Evaluation of QL data done at 017:16:30

The following observations from the last ten days should be available
for review. If there is no comment after the entry, it means the image
