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

Chandra passed through the ninth, tenth, and eleventh eclipses of the season on Nov 20, Nov 22, and Nov 25 respectively, with nominal power and thermal performance.

Chandra press and image releases were issued on Nov 22 describing Chandra and XMM-Newton observations of a white dwarf star, designated KPD 0005+5106 and located at about 1300 light years from Earth, that shows oscillations in brightness with a 4.7 hour period. It emits unusually large amounts of X-rays at higher energies and exhibits an unusually high surface temperature for white dwarfs. The periodic variations indicate that KPD 0005+5106 has an orbiting companion, a planet or a low-mass star, from which material is being drawn and accreted onto the white dwarf.

The schedule of targets for the next week is shown below and includes an observation of QSOJ1131-1231 coordinated with XMM-Newton, observations of ZTF21aanxhjv, which was accepted as a Target of Opportunity on Nov 17, observations of GRB211023B, which was accepted as a Target of Opportunity on Nov 5, and an observation of SN2020ywx, which was accepted as a Target of Opportunity on Nov 1.
