SUMER study #120: Polar plume in Mg X, C I, N V

Remarks: Since the study was executed early in the commissioning phase, the real field-of-view coordinates may not be as commanded.

There was an earlier version of this page without north-south orientation correction.


Mg X (corona, 1 100 000 K)
N V (transition region, 180 000 K)
S II (upper chromosphere, 25 000 K)
H I Ly a (chromosphere, 20 000 K)
C I (lower chromosphere, < 10 000 K)


Detailed information

Spectral windows and images can be found for Images show the subtracted background intensity (in this case, more or less the wing of Lyman alpha), line intensity, shift and width. Information on Mg X and C I is incomplete, because the line signal is noisy and possibly blended.


Animation

To see an animation of the different stages of the Solar atmosphere as recorded by this SUMER study, download the IDL/XDR restore file PP27JAN_MOVIE_XDR.RST (334 KB) and the short IDL program PP27JAN_MOVIE.PRO.

After starting the animation with

IDL> .run pp27jan_movie
the images will go through the five different stages (C I, H I Ly a, S II, N V, Mg X) up and down "like an elevator".
