During the last week Chandra completed the observing schedule as planned. A real-time procedure was executed Nov 10 to perform full-frame dark current readouts of the Aspect Camera Assembly CCD. Additional real-time procedures were executed Nov 13 to turn on SPE-B and gyro B2 in order to provide rate data from which to evaluate the longer-term performance of the reserve gyro B2. Of note this week was the announcement on Nov 8 of CalDB version 4.8.5. The CALDB update includes a new version of the ACIS contamination model. For details see: http://cxc.harvard.edu/caldb/downloads/Release_notes/CALDB_v4.8.5.html The schedule of targets for the next week is shown below and includes observations of Maffei 1 coordinated with NuStar, and observations of AT2019pev, which are follow-ups to a Target of Opportunity which was accepted on Oct 2. |
