Operations CXO Status Report

Friday 3 July 2020 9.00am EDT

During the last week Chandra completed the observing schedule as planned.

Real-time procedures were executed on Jul 1 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer and to perform a diagnostic dump of the Control Processing Electronics (CPE). Real-time procedures were executed during each ground contact to reset the DSN Outage Dead Man Load.

The schedule of targets for the next week is shown below and includes an observation of 3C273 coordinated with NuSTAR and XMM, an observation of Mrk 335 coordinated with NuSTAR and NICER, and observations of SN2020nlb, which was accepted as a Director's Discretionary Time Target of Opportunity on Jun 29.
