Abstract: On August 13, 2006 we performed simultaneous observations in CaIIH, G-band and FeI 6303Å of a complex sunspot in NOAA 10904 with the Swedish Solar Telescope (SST) on La Palma, Canary Islands. From spectropolarimetric scans through the Fei line with the tunable SOUP filter we computed the full Stokes vectors at each pixel of the field of view. At 8:47UT a weak flare eruption (GOES class B7.8) was registered in the line core of CaIIH. We present the changing magnetic field and flow topologies in the underneath penumbral photosphere during the flaring phase. The unmatched spatial resolution of SST observations allows detailed simultaneous mapping of chromospheric and photospheric events.
