[Loops] prominence-cavity eclipse/EUV paper

[Serge Koutchmy]

Dear All,
We were informed that "your manuscript, "Prominence-cavity regions 
observed using SWAP 174A filtergrams and simultaneous eclipse flash 
spectra", by Bazin, C. Koutchmy, S. and Tavabi, E. has been accepted for 
publication in Solar Physics."
A preprint is available at:
http://arxiv.org/abs/1207.1857
Note it is the 1st time that prominences and the so-called cavity often 
seen above eclipse prominences are analyzed using a high spectral 
resolution near the HeI and the HeII lines simultaneously with high S/N 
ratio SWAP filtergrams at 174A and with EIT filtergrams, shedding some 
light on the prominence-corona interacting region physics.
Please find after an abstract of the paper.
Feel free to contact the authors in case some additional material is 
needed.
Enjoy!
Best,
Serge

At the occasion of the last solar total eclipse of 11th July, 2010, we 
studied SWAP filtergrams (from the PROBA2 mission) taken at 17.4 nm in 
the Fe IX/X lines with simultaneous slitless flash spectra in the 
spectral region of 470 nm. These eclipse flash spectra showed many faint 
low excitation emission lines with He I 471.3 nm and He II 468.6 nm 
Paschen {\alpha} chromospheric lines, and correspond to off-limb 
prominences regions observed with space-borne imagers. We aligned and 
stacked 80 individual spectra to study some modulations intensities 
along the continuum between the monochromatic images of the prominences 
without parasitic scattered light. We observed intensity depressions 
around the continuum between prominences in both eclipse and SWAP 
images. The prominence cavities are associated with a depression of the 
plasma density, produced in the interface regions between the corona and 
the prominences. Photometric measurements are shown at different scales 
and different narrow spectral intervals, for both the prominences and 
the coronal background.
