NOAA GOES SATOPS Morning Report 28 Mar 2001

No change in the status of the POES spacecraft; instrument configuration
changes noted below.

NOAA-11 SBUV anomaly actions continue.  As reported yesterday,
the SBUV grating drive began operating in a limited

range (between 247 and 380) at approximately 0243Z on March 27. 
Commanding actions included:

1.  Rev 64486:  Selected SBUV flex memory 1 (mini giant step);
not successful, and reselected SBUV flex memory 0 (normal

ozone).

2.  Rev 64489:  Executed CP to Load flex memory 1 with step
from grating positions 255 to 501 (turnaround in free motion

range).  Executed commands to Select SBUV flex memory 1 (255 to
501 stepping profile).  SBUV grating drive operated in

this range successfully.

3.  Rev 64490:  Executed commands to Select SBUV flex memory
0 (normal ozone) with two cases of full range motion.  The

SBUV did not appear to regain normal function so flex memory 1 was
reselected to allow the SBUV to operate in a

free-motion range overnight.

Todays activities include a re-load of the giant stepping profile into
flex memory 2 to exercise the grating drive in the giant

stepping profile over the normal ozone range.  Engineers are cautiously
optimistic, but it should be noted that the instrument is

now over 12 years old.

POES operations were nominal over the past 24 hours.

DMSP

No change in the status of the DMSP spacecraft.

DMSP operations were nominal over the past 24 hours.

GOES

No change in the status of the GOES spacecraft.

All eclipse operations nominal.  No frame breaks noted.

A short term Hy magnetic field reversal was briefly noted on GOES-10
due to Category G1(minor) to G2 (moderate)

geomagnetic storm conditions due to a Coronal Mass Ejection passage.  
No adverse performance was noted.  Refer to:

http://sec.noaa.gov/NOAAscales/#GeomagneticStorms for information about
geomagnetic storm scales.  Refer to:

http://sec.noaa.gov/today.html of additional data is desired on current
space environmental conditions.

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.

This week, the spacecraft contractor, SS/L, is in town for a series
of COP reviews and launch sims.  Today, the third

GOES-M Launch Sim kicks off and will run through Friday.  Mission
phases to be simulated include Launch, Apogee Motor

Fire#1, Mag Boom/Solar Array Deploy, and Dipole Estimation.

GOES operations were nominal over the past 24 hours.
