Comments: At 1400UT, June 22, the SEC secondary GOES satellite for magnetometer, X-ray, and electron measurements will change from GOES 10 to GOES 11. GOES 12 will continue as the primary SEC GOES satellite. For energetic proton measurements there is no change; GOES 11 will remain the primary SEC GOES satellite and GOES 10 will remain the secondary. This change is necessary because NOAA will be activating GOES 11 as the operational satellite stationed at 135 degrees West geographic longitude in geosynchronous orbit, replacing the aging GOES 10.
