GOES8 Data Missing Because of Satellite Problem
DataStreams:sgpgoes8visX1.a1, sgpgoes8minnisX1.c1, sgpgoes8minnis-acfX1.c1, sgpgoes8X1.a1
Description:
The data was missing over this time period because of a 
problem with the satellite - note discussion below
Subject: URGENT! GOES-8 outage to continue
From: jhawkins@nesdis.noaa.gov (Jamie Hawkins)
Date: Thu, 9 Jan 1997 16:34:14 +0500

NOAA continues to analyze the GOES-8 problem, which now seems to be
unrelated to an electrostatic discharge.  Data now indicate that the
attitude and orbit control computer (AOCE#2) is not receiving telemetry from
one of two momentum wheels which keep the spacecraft facing the earth
propoerly.  A fix has been identified which will require using a back-up
momentum wheel configuration known as L2.  

To begin L2 operations, NOAA will bring GOES-8 out of safe hold at
approximately 5:00PM EST (22:00UTC) tomorrow, Friday January 10th.  About
two hours later, around 7:00 PM EST (00:00 UTC Saturday), imager and sounder
GVAR data should begin flowing from the satellite.  Operational products
from NOAA for the National Weather Service should resume at that time.  

However, ALL USERS SHOULD NOTE that it may take 48 hours or longer for
accurate navigation and registration to return to GOES-8 imagery.

We will keep you informed of any chnages in this scheduled fix during the
day Friday.
