PLAN
----
Continue running load MAR0611B. Doing obsid 12444, an ACIS-LETG ToO
observation of 4U1820-30 to get spectra of bright X-ray bursts to
study expansion of the photosphere, and measure absorption lines of
nucleosynthesis products.

NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:

Three supports over the past day. No issues. One stored command
sequence uplinked, on-board loads good until 071:08:22.

MAR1411 products expected out tomorrow.

There were two Solar coronal mass ejections yesterday.  A partial halo
CME could reach Earth on March 9/10.  It will very likely be overtaken
by a very fast CME which could reach Earth on March 9 and cause minor
to severe geomagnetic storming.  Electrons and hard proton rates are rising.

Quick look data:
