Operations CXO Status Report

Friday 6 May 2016 9.00am EDT

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

An aspect camera dark (ACA) current calibration was performed from the on-board loads on May 4. An assessment of the data is underway.

A real-time procedure was executed on May 5 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer. A second real-time procedure was executed on May 5 to disable the multiple stars suspected filter in the ACA Data Processing subfunction running in the on-board computer. A recent change has mission operations conducted with the filter disabled at all times but commanding associated with the ACA dark current measurement re-enabled the filter.

The schedule of targets for the next week is shown below and includes observations of 2MASS J13413291+0805048 and SDSS J1556+1124 coordinated with ground-based observatories and an observation of ESO 509-G038 coordinated with NuSTAR
