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…
Critical decay index for eruptions of 'short' filaments
Boris Filippov
Model of a partial current-carrying torus loop anchored to the photosphere is analyzed. Conditions of the catastrophic loss of equilibrium are considered and corresponding value of…
Mass of prominences experiencing failed eruptions
B. Filippov
A number of solar filaments/prominences demonstrate failed eruptions, when a filament at first suddenly starts to ascend and then decelerates and stops at some greater height in th…
Failed prominence eruptions near 24 cycle maximum
B. Filippov
We analyze 16 failed filament eruptions observed near 24 solar cycle maximum from May 2013 to July 2014. No significant rotation of filament spines is observed during the ascent in…
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…
Difference of source regions between fast and slow coronal mass ejections
B. Filippov
Coronal mass ejections (CMEs) are tightly related to filament eruptions and usually are their continuation in the upper solar corona. It is common practice to divide all observed C…
