The Sun Online and solar activity. September 3, 2014

A partial halo CME was detected yesterday in association with the eruption of a long filament in the northern hemisphere. The CME first appeared in the SOHO/LASCO C2 field of view at 16:36 UT, had angular width around 190 degrees and the projected plane-of-the-sky speed around 450 km/s. Despite
the position of the CME source region not far from the solar disk center, the bulk of the CME material went northward of the ecliptic plane. The arrival of the corresponding ICME and even of the ICME-driven shock at the Earth is unlikely, so no resulting geomagnetic disturbance is expected. This CME is a far side event as seen from Venus, so it will not affect Venus either.
