NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
2 Supports completed in the last 24 hours (total time: 5.8 hours)
2 SSR dumps
DSN DR, M113194, DSS-54, Station unable to support Chandra,
S-band transmitter failure, station has been RED since 024/1006z
with no notification to the Chandra team. Added time to following
support for SSR recovery (SSR-B will rollover at 027/0927z).
CAP 1510, DSN Outage Deadma Load, Part 2 only ran
successfully at each support, 026/1454z.
Radiation:
Solar activity is expected to be very low on days one, two,
and three (27 Jan, 28 Jan, 29 Jan).
MP:
Feb0121 loads will be sent out today.
Eng:
No issues.
GOT:
No issues.
