KOZ (KEEP OUT ZONE) / ECLIPSE
GOES satellites encounter two periods during the year in which they are in Earth's shadow. Known as the Eclipse (ECL) season, these periods require the spacecraft to be completely dependent upon batteries for a maximum of 72 minutes daily. Eclipses occur approximately from late February to mid-April, and from late August to mid-October.
GOES-13/14/15 - There is a significant risk of light from the sun directly entering the scanners and causing degraded products as the spacecraft enters and leaves the Earth's shadow, requiring a special algorithm to be applied to the Imager products. In some instances shifting or cancelling the frame is necessary. This is known as the "Stray Light Zone (SLZ)." The seasonal charts describe the GOES-East and GOES-West Imager and Sounder scan frames that are canceled or shifted due to SLZ.
