A fast, far-sided halo CME was observed beginning at 04:36 UTC on 23 July in coronagraph imagery. The event originated from old Region 2665 (S06, L=111) which was responsible for two M-class flares during its rotation across the visible disk. The imagery above shows the event as seen from the NASA STEREO A spacecraft (left and right images) and the coronagraph on the NASA SOHO spacecraft (center). This CME is on the opposite side of the Sun and will not be geoeffective.
