The data are sampled along the orbit track and then interpolated in time and position for the rest of the polar region. This interpolation is responsible for the curved block-shaped artifacts in the images.    POES data showing particle fluxes at or near their lowest levels. Available formats:   2560 x 1920     TIFF 6 MB   320 x 240         JPEG 8 KB    The particle flux increases dramatically over the polar cap, as they are carried Earthward along the magetic field lines.
