Do ACIS CTI on perigee egress, then obsid 3756, an ACIS-S/HETG observation of the X-ray bright weak-lined T Tauri star HDE 283572, the pre-main sequence stage of a massive A-type star.

NOTES/ISSUES/PROBLEMS Looks like ACIS will be more than 2 deg C warm at the start of obsid 3756. Coot hung, due to a cable partially pulled out. Dan Rehner rebooted, and Cambridge ops restored telemetry connection. From the 9am status meeting: Nine supports over the weekend. No issues, first two segments of OCT2003B were uplinked, on-board loads good until 296:07:32. Mission planning products not ready today. No engineering, science, or ground system news.
