Continue running load MAY1505A. Finish obsid 5835, an ACIS-I GTO
observation of the cluster of galaxies cl1354-0221. Then do 6282, an
ACIS-S/HETG observation which is a continuation of the coordinated
observation of the RS CVn star Sigma Gem with Hubble and ground based radio.

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the past day.  DSS-27 came up 28 minutes late, due
to an antenna problem which required manual maintenance to fix. All
support requirements were met. One SCS uplinked, on-board loads good
until 141:13:20.
Loads are being rebuilt to accomodate a new fast ToO to look at the
HETE X-ray flasher XRF050509C. In the absence of direction to the
contrary, the ToO for 3C454.3 is not being planned. No load review today.

A preapproved CAP to disable SCS 29 is planned for this afternoon's
pass.

ACE soft solar proton rates continue to decrease slowly. Fluxes are
about 1000. A frontsided, partial halo CME was seen at 13:50 UT
yesterday.
