Pass through perigee and measure cti on egress. Then do obsid 7594, a cycle 8 ACIS-S observation of the transient Anomalous X-ray Pulsar XTE J1810-197 to monitor its flux, spectrum, and spin. Then do obsid 9403, an ACIS-I observation of the cluster of galaxies SC1324+3051 to study AGN and feedback in a supercluster at z=0.7.

Three stored command segments uplinked, on-board loads good until 081:12:30. MAR2408 products were circulated last Friday, for a load review today at 2pm (on 1159). There is some DSS ground station downtime, so alternate contacts are being arranged. Sun is extremely quiet, GOES x-rays and ACE protons both at background levels.
