| Abstract: |
Broad-band filter linear polarization movies in the green and the
orange spectral intervals were used to derive the 2D distributions
of the relative color index RCI for the corona
of July 22, 2009 in the range <1.5 R☉. Different
RCIs for different coronal structures are
revealed. Polar plumes and the bottom of the streamers are traced
by the blue color. The diffuse red background is not changing with
distance and is seen between the polar plumes and streamers.
Radially moving coronal electrons and the sky brightness are noted
to be responsible for the color variations. |
