PLAN
----
Continue running load FEB2607C. Finish the ascending CTI measurement,
then resume ACIS-S/HETG observation of he accreting young star TW Hya,
obsid 7436, to distinguish X-ray emission from a hot corona vs. an
accretion shock, and to probe the density and structure of the
magnetic regions.

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Two supports over the past 24 hours, no issues. One stored command
segment was uplinked, on-board loads good until 063:08:46
MAR0507A products out yesterday for a load review at 2pm today.
Soft solar protons up a factor of ~20, to ~400, but solar activity is
extremely low so this is probably not of concern.
