Correlation of Anomaly Rates in the Slovak Electric Transmission Grid with Geomagnetic Activity
Tatiana Vybostokova, Michal Svanda
The induction of electric currents in electric power distribution networks is a well-known effect of Earth-directed eruptive events. Inspired by recent studies showing that the rat…
Large-scale photospheric motions determined from granule tracking and helioseismology from SDO/HMI data
Th. Roudier, M. Svanda, J. Ballot +2
Large scale flows in the Sun play an important role in the dynamo process linked to the solar cycle. The important large scale flows are the differential rotation and the meridiona…
Estimate of the regularly gridded 3D vector flow field from a set of tomographic maps
M. Svanda, M. Kozon
Time--distance inversions usually provide tomographic maps of the interesting plasma properties (we will focus on flows) at various depths. These maps however do not correspond dir…
Polar cap magnetic field reversals during solar grand minima: could pores play a role?
M. Svanda, A. S. Brun, Th. Roudier +1
We study the magnetic flux carried by pores located outside active regions with sunspots and investigate their possible contribution to the reversal of the global magnetic field of…
Structure and evolution of solar supergranulation using SDO/HMI data
Th. Roudier, M. Švanda, M. Rieutord +3
Context: Studying the motions on the solar surface is fundamental for understanding how turbulent convection transports energy and how magnetic fields are distributed across the so…
Dynamics of the solar atmosphere above a pore with a light bridge
M. Sobotka, M. Švanda, J. Jurčák +3
Context: Solar pores are small sunspots lacking a penumbra that have a prevailing vertical magnetic field component. They can include light bridges at places with locally reduced m…
