Description
The Space Weather Follow-On (SWFO) program will provide operational solar-coronal images and in situ solar wind measurements to the science community and to space weather information users. Here we first give status updates on the Compact Coronagraph 1 (CCOR-1) onboard the Geostationary Operational Environmental Satellite 19 (GOES-19) since its June 25, 2024 launch. The Post-Launch Test (PLT) started on July 25 and is planned to end in February 2025 with the instrument’s Provisional Peer-Stakeholder Product Validation Review (PS-PVR). Earthshine characterization and mitigation of near-equinox eclipse occultations are two key calibration/operation objectives. During this time, CCOR-1 will provide its first images of coronal mass ejections, helmet streamers, pseudostreamers, and other coronal structures over a range of 3.7-17 R_Sun. Several of these observations will be used in intercalibration with LASCO C2 and C3 and in synergistic comparisons with other solar viewing instruments from space- and ground-based platforms.
Next, a second coronagraph, CCOR-2, and three in situ instruments, including a magnetometer suite (MAG), a plasma sensor (SWiPS), and a suprathermal particle sensor (STIS), will operate on board the SWFO-Lagrange 1 (SWFO-L1) observatory at the Sun-Earth Lagrange 1 point (L1) with a 2025 planned launch. In fall 2024, SWFO-L1 will have completed its environmental testing, and end-to-end tests will be applied to the space- and ground-segments of the mission. We give an overview of the science goals for SWFO-L1 and synergies with IMAP, DSCOVR, ACE, Aditya-L1, and other spacecraft at L1. We will briefly describe the data products, outlining types and levels, formats, and latency to users. Finally, we discuss data access, including the use of the Space Weather Portal (SPOT) developed at the National Centers for Environmental Information (NCEI) for SWFO and other missions; and documentation in terms of algorithm documents and user guides.
