| During the last week Chandra completed the observing schedule as
planned.
Chandra passed through the second and third eclipses of the spring season on Apr 17 and 20 respectively, with nominal power and thermal performance. Two real-time procedures were completed on Apr 15; the first to update the on-board ephemeris and the second to uplink an update to the on-board gyro scale-factor and alignment matrix. Real-time procedures were executed on Apr 16 to dump OBC-A memory as a follow-up to the gyro scale-factor and alignment matrix patch. The dump will be used to update the baseline memory image maintained on the ground. The schedule of targets for the next week is shown below and includes one of the series of the Crab Nebula Target of Opportunity observations, observations of FK Com coordinated with the HST, and an observation of PKS 2155-304 coordinated with XMM-Newton and Suzaku. |
