K-Cor White Light Level 1 Data
K-Cor

Level 1 data: FITS images are processed to remove instrumental effects and sky polarization, but intensities are not yet fully calibrated. The GIF images contain a power law scaling.

Full resolution and Low-res cropped GIFs available!

K-Cor White Light Level 1 normalized radially graded filter (NRGF) Data
K-Cor

Level 1 (nrgf) data: FITS and GIF Level 1 images with a normalized radially graded filter (nrgf, Morgan et al. 2009, adapted by Silvano Fineschi and Sarah Gibson for KCor use) to maximize image contrast. These data are ideal for measuring positions of coronal structures such as CMEs and helmet streamers.

The cadence of these specially processed images is 2 minutes. If you require 15 second cadence, please contact us.
