Evolution of a single event detected with the Hinode/SP time series. Each column corresponds to a different time in its evolution. The first row displays the continuum signal from Hinode/SP, the second row shows the CN broadband image from Hinode/BFI, the third row displays the Fe i 6302.5 Å magnetogram from Hinode/SP, and the fourth row shows the Ca ii h broadband images from Hinode/BFI. We have also highlighted the pixels with blue- and red-shifted single-lobed Stokes V profiles with blue and red crosses, respectively. Pixels with linear polarization signals above 0.01 I_c are indicated with green crosses.
