A partial halo CME with angular width of 158 degrees and the speed 558 km/s
was detected by CACTUS at 15:24 UT yesterday. The CME is frontsided, it was
initiated by the filament eruption at the NW part of the solar disk. The
eruption is associated with C3 long duration flare and the minor proton
event. Simulation of the CME is currently in progress in order to determine
it's geoeffective component.
