Evolution and Flare Activity of Delta-Sunspots in Cycle 23
Kan Takizawa, Reizaburo Kitai
The emergence and magnetic evolution of solar active regions (ARs) of beta-gamma-delta type, which are known to be highly flare-productive, were studied with the SOHO/MDI data in C…

Magnetic helicity transported by flux emergence and shuffling motions in Solar Active Region NOAA 10930
Y. Zhang, R. Kitai, K. Takizawa
We present a new methodology which can determine magnetic helicity transport by the passage of helical magnetic field lines from sub-photosphere and the shuffling motions of foot-p…
