Scientific paper

We apply the time-distance helioseismology technique to obtain 3D tomographic images of sound-speed variations and mass flow velocity maps below the visible surface of the Sun, for emerging and evolving magnetic active regions. In particular, using uninterrupted helioseismology observations from the MDI instrument on the SOHO spacecraft we investigate the development of the large complex of activity NOAA 10484-10488, which produced a series of giant proton flares in October, 2003. The flow maps reveal new interesting properties, such as strong divergent and shearing flows associated with the magnetic flux emergence and flaring activity. Using the sound-speed image we attempt to find the common roots and links of these remarkable active regions.
