GOES "single chord" operations, made necessary by lunar and solar
intrusions at the edge of
the Earth disk, impact navigation and registration for short periods.
Users of GOES GVAR data
will see variable errors during periods of single chord operations as noted
below.
Single Chord Operations for the Bevel effect are listed when applicable.
Bevel effect operation is
intended to avoid a seasonal spacecraft pointing problem with all GOES
spacecraft caused by the
sun's light reflecting into the earth sensor.
Following are times of GOES-8 single chord operations for the period August
28, 2000 to September 26, 2000.
