Operations CXO Status Report

Friday 15 February 2008 8.00am EST

During the last week the observing schedule was replanned to include an observations of GRB 080207 (Dark-GRB1) that was accepted as a fast turn-around Target Of Opportunity (TOO) on Feb 11. Loads were replanned and uplinked on Feb 14 for an observation on Feb 16. An observation of the Carina South Pillar was impacted by the TOO and will be rescheduled in a later load.

A real-time procedure was completed on Feb 13 to update the on-board Ephemeris.

A Chandra press release was issued on Feb 13 describing the possible detection of a binary star system that was later destroyed in a supernova explosion. For further details see:

The schedule of (many) targets for the next week is shown below and includes an observation of 2MASS J0746425+200032 coordinated with the VLA.
