Operational Level 1A image data from the Compact Coronagraph-1 (CCOR-1) aboard the GOES-19 spacecraft. The data consist of processed white-light coronagraph images of the solar corona generated from Level 0B data. The images are normalized by exposure time and converted to mean solar brightness (MSB) using a photometric calibration factor. The images have dimensions of 2048 by 1920 pixels and are provided in FITS format. Unlike the Science Level 1A product, the Operational Level 1A processing does not include the additional science-quality corrections such as bias, non-linearity, and vignetting corrections. The nominal cadence is approximately 15 minutes.

CCOR-1 Operational Level 1A white-light coronal intensity stored in FITS extension #1 as a 2048 x 1920 pixel compressed floating-point image array. The image is expressed in mean solar brightness (MSB) and uses helioprojective solar coordinates with a zenithal polynomial (ZPN) projection. The plate scale is approximately 19.33 arcsec per pixel at the reference point. The CCOR-1 bandpass has a measured full width at half maximum (FWHM) of approximately 470 to 740 nm. The reference time is specified by the DATE-OBS FITS keyword.
