NOAA GOES SATOPS Morning Report 2 April 2001

SATOPS MORNING REPORT – April 2, 2001

No significant effects noted on any spacecraft noted from high solar/geomagnetic
activity over the weekend. Some momentum
buildup was observed on some of the LEO spacecraft and some brief Hy
magnetic field reversals noted on the GOES
spacecraft. All of these effects have been noted in the past and have not resulted
in adverse conditions on the spacecraft.
Additional information on the current state of the space environment can be
observed on: http://www.sec.noaa.gov/today.html

POES

No change in the status of the POES spacecraft.

NOAA-11 SBUV anomaly actions will continue today on revs 64571 and
64572. On Friday, the total ozone wavelengths
were loaded into flex memory 3. The SBUV grating drive remained parked at
position 501 over the weekend.

NOAA-16 rev 2684 / W at 1739Z on March 30: GAC4B failed to lock on the
MSB on both the “A” and “B” antenna. The
WCDAS believes this problem is due to a change in 13 meter software
parameters. Recorder management prevented replay
from the spacecraft. 100% of GAC4B was lost.

NOAA-14 rev 32211 / F at 0322Z on March 31: GAC5B noisy from
spacecraft with 98.8% of the expected data received.
A second transfer yielded only 73.9% of the expected data. Another recovery
attempt from the spacecraft was not be
possible due to recorder scheduling management.

NOAA-14 rev 32217 / F at 1349Z on March 31: LAC3A received noisy from
the spacecraft with 97% of the expected data
recovered. CEMSCS declined a replay attempt.

NOAA-14 rev 32239 / F at 0259Z on April 2: LAC2B noisy from spacecraft
with 97.8% of the expected data recovered.
No retransmittal required.

POES operations were nominal over the past 72 hours.

DMSP

No change in the status of the DMSP spacecraft.

DMSP operations were nominal over the past 72 hours.

GOES

No change in the status of the GOES spacecraft.

All eclipse operations nominal. No frame breaks noted.

Brief Y-axis mag field polarity reversals on the GOES spacecraft sensed on
March 31 due to solar-induced geomagnetic
activity; no adverse effects noted.

To review the eclipse schedules for the GOES-8 and GOES-10 spacecraft, refer
to:
http://www.ssd.noaa.gov/SSD/GOES/eclipse.html to identify images canceled to
satisfy eclipse or instrument keep-out-zone
(KOZ) requirements.

GOES operations were nominal over the past 72 hours.
