New Coronagraph Data Available from NOAA

We are pleased to announce that data are now available from NOAA’s Compact Coronagraph (CCOR-1). Two CCORs have been built by the Naval Research Laboratory as a part of NOAA’s Space Weather Follow On (SWFO) program. CCOR-1 was incorporated onto the GOES-19 spacecraft. CCOR-2 is incorporated onto the SWFO spacecraft that plans to launch in Fall 2025. CCOR-1 has been collecting data since September 2024. The public archive extends to February 24, 2025, when CCOR-1 was declared operational. The data have been calibrated via a collaboration of scientists working in the Space Weather Prediction Center and the National Centers for Environmental Information. CCOR-1 data has gone through two internal reviews, and the data are ready for scientific use. The instrument’s FOV is similar to LASCO C3. It provides a 1920×2048 pixel image of the white light corona (total brightness) at a highly regular 15 minute cadence. Several different data products are available. Resources describing the data and current access links can be found at: https://www.ncei.noaa.gov/products/space-weather/swfo. Retrospective authoritative products are currently available via AWS at https://noaa-nesdis-swfo-ccor-1-pds.s3.amazonaws.com/index.html#SWFO/GOES-19/CCOR-1/. An improved user interface should be available within 4 months. Operational data products produced by SWPC are available at: https://services.swpc.noaa.gov/products/ccor1/.
