Observational study of chromospheric heating by acoustic waves
V. Abbasvand, M. Sobotka, M. Švanda +9
Aims. To investigate the role of acoustic and magneto-acoustic waves in heating the solar chromosphere, observations in strong chromospheric lines are analyzed by comparing the dep…
Immediate and delayed responses of power lines and transformers in the Czech electric power grid to geomagnetic storms
Michal Švanda, Didier Mourenas, Karla Žertová +1
Eruptive events of solar activity often trigger abrupt variations of the geomagnetic field. Through the induction of electric currents, human infrastructures are also affected, nam…
Evolution of photospheric flows under an erupting filament in the quiet-Sun region
Jiří Wollmann, Michal Švanda, David Korda +1
We studied the dynamics of the solar atmosphere in the region of a large quiet-Sun filament, which erupted on 21 October 2010. The filament eruption started at its northern end and…
Chromospheric Heating by Acoustic Waves Compared to Radiative Cooling: II -- Revised Grid of Models
Vahid Abbasvand, Michal Sobotka, Petr Heinzel +4
Acoustic and magnetoacoustic waves are considered to be possible agents of chromospheric heating. We present a comparison of deposited acoustic energy flux with total integrated ra…
