Speed of Meridional Flows and Magnetic Flux Transport on the Sun
M. Svanda, A. G. Kosovichev, J. Zhao
We use the magnetic butterfly diagram to determine the speed of the magnetic flux transport on the solar surface towards the poles. The manifestation of the flux transport is clear…
Initial Helioseismic Observations by Hinode/SOT
Takashi Sekii, Alexander G. Kosovichev, Junwei Zhao +12
Results from initial helioseismic observations by Solar Optical Telescope onboard Hinode are reported. It has been demonstrated that intensity oscillation data from Broadband Filte…
Time-Distance Imaging of Solar Far-Side Active Regions
Junwei Zhao
It is of great importance to monitor large solar active regions in the far-side of the Sun for space weather forecast, in particular, to predict their appearance before they rotate…
Comparison of large-scale flows on the Sun measured by time-distance helioseismology and local correlation tracking technique
Michal Svanda, Junwei Zhao, Alexander G. Kosovichev
We present a direct comparison between two different techniques time-distance helioseismology and a local correlation tracking method for measuring mass flows in the solar photosph…
