Dear All, <br>
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."<br>
A preprint is available at:<br>
<a class="moz-txt-link-freetext" href="http://arxiv.org/abs/1207.1857">http://arxiv.org/abs/1207.1857</a><br>
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. <br>
Please find after an abstract of the paper. <br>
Feel free to contact the authors in case some additional material is
needed. <br>
Enjoy!<br>
Best,<br>
Serge<br>

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.
