We observed two surges in H-alpha from the super-active region NOAA 10484.The first surge was associated with an SF/C4.3 class flare. The second one wasa major surge associated with a SF/C3.9 flare. This surge was also observedwith SOHO/EIT in 195 angstrom and NoRh in 17 GHz, and showed similar evolutionin these wavelengths. The major surge had an ejective funnel-shaped spraystructure with fast expansion in linear (about 1.2 x 10^5 km) and angular(about 65 deg) size during its maximum phase. The mass motion of the surge wasalong open magnetic field lines, with average velocity about 100 km/s. Thede-twisting motion of the surge reveals relaxation of sheared and twistedmagnetic flux. The SOHO/MDI magnetograms reveal that the surges occurred at thesite of companion sunspots where positive flux emerged, converged, and canceledagainst surrounding field of opposite polarity. Our observations supportmagnetic reconnection models for the surges and jets.
