Compact Coronagraph-1 (CCOR-1)
NOAA GOES-U compact coronagraph instrument for detecting and characterising coronal mass ejections from geostationary orbit.
Compact Coronagraph-1 (CCOR-1) images the solar corona from geostationary orbit aboard GOES-19. It helps detect and characterize coronal mass ejections (CMEs), large expulsions of plasma and accompanying magnetic field from the corona. The instrument is designed to capture white-light imagery of the upper solar corona and resides on the spacecraft's Solar Pointing Platform.[1][2]
CCOR-1 images the corona from 3.7 to 17 solar radii, with spatial resolution of about 50 arcseconds. Its visible wavelength range is 480 to 730 nm, and its image latency is 15 minutes.[1] Sequences of CME images can be used to determine their size, velocity and density.[2]
The instrument's primary data product is coronal white-light intensity. It supports space-weather forecasting, and provisional CCOR-1 data products were released on February 24, 2025.[2][1]
