Space Weather Follow-On (SWFO) is a NOAA environmental satellite program under development by OPPA. Its mission is to provide space weather observations to enable space weather forecasting by NOAA. SWFO will make direct, in-situ, measurements of the solar wind thermal plasma and magnetic field “up-stream” of the Earth. In addition, SWFO will observe the Sun’s corona to detect expulsions of plasma and magnetic field, called Coronal Mass Ejections (CMEs), which may be directed towards the Earth. The data produced by SWFO will help NOAA provide watches and warnings for space weather events that can disrupt the electrical power grid and communications systems as well as navigation and timing systems like the Global Positioning System (GPS). The SWFO program is comprised of two projects: CCOR on GOES U spacecraft and the Space Weather Follow-On L1 mission (SWFO-L1).
