Operations CXO Status Report

Friday 16 March 2018 9.00am EDT

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

A Chandra image release was issued on Mar 14 describing observations of the Crab nebula. The Crab has been observed multiple time over the more than 19 years of the Chandra mission. These allow us to measure changes in its structure. The latest image of the Crab is a composite with X-rays from Chandra, NASA's Hubble Space Telescope and NASA's Spitzer Space Telescope. The extent of the X-ray image is smaller than the others because extremely energetic electrons emitting X-rays radiate away their energy more quickly than the lower-energy electrons emitting optical and infrared light. See: for details.

The Chandra proposal deadline is today, Mar 16, it was postponed by one day due to a snowstorm in Boston.

The schedule of targets for the next week is shown below and includes an observation of MAXI J1813-095, which is a follow-up to a Target of Opportunity which was accepted on Feb 21 and is coordinated with NuSTAR.
