Polarimetric Studies of a Fast Coronal Mass Ejection
Marilena Mierla, Bernd Inhester, Andrei N. Zhukov +4
In this work we performed a polarimetric study of a fast and wide coronal mass ejection (CME) observed on 12 July 2012 by the COR1 and COR2 instruments onboard Solar TErrestrial RE…
Polar regions activity and the prediction of the height of the solar cycle 25
S. Koutchmy, B. Filippov, E. Tavabi +2
The forthcoming solar cycle (SC) 25 was beleived to be rather low when using the sunspot number (SN) as a measurement of the level of activity. The most popular prediction was made…
Solar Total Eclipse of 21 August 2017: Study of the Inner Corona Dynamical Events Leading to a CME
Boris Filippov, Serge Koutchmy, Nicolas Lefaudeux
Total solar eclipse (TSE) coronal large and small scale events were reported in the historical literature but a definite synoptic coverage was missing for studying a relationship w…
New deep coronal spectra from the 2017 total solar eclipse
S. Koutchmy, F. Baudin, Sh. Abdi +2
Total eclipses permit a deep analysis of both the inner and the outer parts of the corona using the continuum White-Light (W-L) radiations from electrons (K-corona), the superposed…
Chromospheric peculiar off-limb dynamical events from IRIS observations
E. Tavabi, S. Koutchmy
To study motions and oscillations in the solar chromosphere and at the transition region (TR) level we analyze some extreme Doppler shifts observed off-limb with the Interface Regi…
Proper Motions of Sunspots' Umbral Dots at High Temporal and Spatial Resolution
Hadis Goodarzi, Serge Koutchmy, Ali Adjabshirizadeh
To deepen the analysis of the photometric properties of the umbra of a sunspot, we study proper motions of small features such as umbral dots (UDs) inside a single sunspot observed…
