During the last 48 hours Chandra observed TON-S-180 with
ACIS-S/LETG, and LP 944-20 with ACIS-S.
A real-time procedure was completed successfully to test a
backup SI safing script. The script safed the gratings, HRC and
ACIS, and moved the SIM to the HRC-S in-focus position as
expected. The Dec 19 mission load review was held today and
approval is expected tomorrow.
During the next 48 hours Chandra will pass through the
radiation belts with associated CTI measurements, NGC 253 with
ACIS-S, TOO SN (A5) with ACIS-S and start a long observation of
Lambda And with ACIS-S and HETG.
The spacecraft systems continued to operate nominally.
