Measuring ACIS CTI following perigee passage. Then do obsid 3045, an HRC-S/LETG observation of NGC5548, for the entire orbit 339.

Ascending through 72539 km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS For 3045, the snapshot shows the SIM FApos -990 in red. Is this an incorrect setting or a problem? I believe -990 is the standard location for HRC-S/LETG observations. From the 9am status meeting: On board loads good for remainder of week, until 020:18:15. JAN2102D is completed and awaiting signoff. (But is at risk if we need to change next week's LETG obsid 3383 to get better coordinated coverage with HST. IF so, we need to treat it as a TOO.) Couldn't set up ASVT yesterday to continue test and debug of the dead dumps. Will try again today. Meeting at 3pm EST today for managers and engineering leads on Knowledge Capture (of Chandra Design and Test info) and maintenance.
