GOES Eclipse Schedules

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.

  • 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.


    Fall 2017 Solar RFI predicted times

    Wallops, Fairbanks and SOCC receiving antennas may experience periods of Solar RFI as predicted below. Solar RFI can cause loss of telemetry lock and command capability. The GOES-East and GOES-West command schedules will include comments for the predicted time periods. SEM Calibrations for GOES-NIP should be canceled during this period.

    Operations Crew should monitor range data on OATS after the RFI period is over. If OATS is not receiving range data in the nominal 15 minute interval a ground calibration on the SPS is required. The operations crew should find the earliest opportunity in the schedule and request the SPS operator to perform a ground calibration on the SPS during this hole in the schedule. After the ground calibration is complete, verify the next nominal 15 minute range is sent to OATS. Notify INR engineering of the missing range data.
