GOES Eclipse Schedules - Spring 2017

KOZ (KEEP OUT ZONE) / ECLIPSE
The GOES satellites encounter two periods, during the year, in which the satellites are in the Earth's shadow. Known as the Eclipse (ECL) season, these periods require the spacecraft to be totally dependent on onboard batteries for a maximum of 72 minutes daily. Eclipse's occur from approximately late February to mid April and from late August to mid October.

GOES-13/14/15 - There is a significant risk of the sun light 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 cases 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.

  • Full Disk Scan During Eclipse
    There will be no Full Disk Coverage for GOES East or GOES West
    this eclipse season since we will not have an outage of more
    than 15 minutes.
