COSMO K-Coronagraph (K-Cor) White Light Polarization Brightness Images

K-Cor provides polarization brightness (pB) images of the Sun's white light corona over a full field-of-view from 1.05 to 3 solar radii. Images are 16-bit 1024x1024, with 5.6 arcsec pixels at a 15 second time cadence. Data are available on the MLSO web page ~15 minutes after acquisition and can be used to identify coronal mass ejections (CMEs) in near realtime.
