NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
4 Supports Completed in the last 24 hours (Total time: 9.2 hours)
3 SSR dumps
Loads good through: 2024:027:23:50:18.000
CAP's / Procedures Run:
CAP # | Time | Title / Description / Notes
[1729]| 025/0043z | Post Normal Sun Mode SCS26 Manipulation
[1730]| 025/1902z | Command a 3-CCD (option B) ACIS-I ECS measurement via RTS,
template version 1.8
DSN DR's Created: DR Number| Station| Problem| Cause| Action
[M116693]|DSS-65| Unable to support Chandra| Failed Transmitter| Moved
comm to DSS-54 (Later)
Radiation:
Solar activity is expected to be low with a chance for M-class flares and a
slight chance for an X-class flare on day one (26 Jan) and expected to be low
with a chance for M-class flares on days two and three (27 Jan, 28 Jan).
MP:
Jan26 loads approved and uplinked.
Jan29 loads in work for release later today or tomorrow.
ENG:
Spacecraft continues to cool. There were several thermal limit
violations due to the time at normal sun, including HRC. These
should not affect the mission going forward.
GOT:
No issues.
