Photometric properties of new solar H alpha commercial Fabry-Perot etalons. Application to the analysis of the chromospheric fringe
Cyril Bazin, Serge Koutchmy
We consider the use of the commercially available Fabry-Perot etalons (FP) for the imaging of the solar chromosphere in the H alpha line of HI. Three etalons of 40, 60 and 90 mm di…

Prominence-cavity regions observed using SWAP 17.4 nm filtergrams and simultaneous eclipse flash spectra
C. Bazin, S. Koutchmy, E. Tavabi
SWAP images from PROBA2 taken at 174 Å in the Fe IX/X lines are compared with simultaneous slitless flash spectra obtained during the solar total eclipse of 11 July, 2010. Myriads…
