Sympathetic Quiet and Active Region Filament Eruptions

Autor: Koleva, Kostadinka, Devi, Pooja, Chandra, Ramesh, Joshi, Reetika, Duchlev, Peter, Dechev, Momchil

We present the observations of three sympathetic filament eruptions occurring on 19 July 2015 namely F1, F2, and F3. The events were observed in UV/EUV wavelengths by Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory and by Global O

Eruptions from coronal hole bright points: observations and non-potential modelling

Autor: Madjarska, Maria S., Galsgaard, Klaus, Mackay, Duncan H., Koleva, Kostadinka, Dechev, Momchil

Publikováno v: A&A 643, A19 (2020)

A single case study of a CBP in an equatorial coronal hole with an exceptionally large size is investigated to extend our understanding of the formation of mini-filaments, their destabilisation and the origin of the eruption triggering the formation

The sub- and quasi-centurial cycles in solar and geomagnetic activity data series/v.3

Autor: Komitov, Boris, Sello, Stefano, Duchlev, Peter, Dechev, Momchil, Penev, Kaloyan, Koleva, Kostadinka

The subject of this paper is the existence and stability of solar cycles with durations in the range of 20-250 years. Five types of data series are used: 1) The Zurich series (1749-2009 AD), the mean annual International sunspot number Ri, 2) The Gro
