August 26 -- GOES Satellite Eclipse Season

Eclipse season for the GOES 10, 11, and 12 spacecraft begins on August 23, September 1, and August 30 respectively and continues for about 40 days. Maximum daily outages of about 65 minutes are reached in the middle of the eclipse season.

Proton Flux plot is GOES-11 data
Electron Flux and GOES Hp plots are GOES-12 and GOES-11 data

The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. Click on a data panel to open an updating secondary window. An updating Satellite Environment Plot window is also available.

Although these data are of interest to the satellite community, they do not include all parameters and energy ranges known to be associated with satellite anomalies.
