Filament eruption deflection and associated CMEs

K. Koleva, R. Chandra, P. Duchlev +1

We present the observations of a quiescent filament eruption and its deflection from the radial direction. The event occurred in the southern solar hemisphere on 2021 May 9 and was…

Sympathetic Quiet and Active Region Filament Eruptions

Kostadinka Koleva, Pooja Devi, Ramesh Chandra +3

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 I…

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

Maria S. Madjarska, Klaus Galsgaard, Duncan H. Mackay +2

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 de…

Homologous prominence non-radial eruptions: A case study

P. Duchlev, K. Koleva, M. S. Madjarska +1

The present study provides important details on homologous eruptions of a solar prominence that occurred in active region NOAA 10904 on 2006 August 22. We report on the preeruptive…

Hα spectroscopy and multiwavelength imaging of a solar flare caused by filament eruption

Z. Huang, M. S. Madjarska, K. Koleva +4

We study a sequence of eruptive events including filament eruption, a GOES C4.3 flare and a coronal mass ejection. We aim to identify the possible trigger(s) and precursor(s) of th…

Emission line variability in the spectrum of V417 Centauri

K. A. Stoyanov, R. K. Zamanov, M. F. Bode +4

We report high resolution spectral observations of the yellow symbiotic star V417 Cen obtained in 2004. We find that the equivalent widths of the emission lines decreased, while th…
