An M1.7 flare occurred from NOAA active region 2891 peaking at 3:01UT this morning and was associated with an on disc dimming. SoHO LASCO C2 coronagraph images now show an asymmetric full halo CME from 2:48UT onwards. Its speed projected on the plane of the sky is around 650 km/s on average with larger speeds of around 1100km/s in the Northern direction. STEREO COR2 coronagraph images are currently not (yet) available to provide better 3D velocity estimates. The CME is certainly Earthbound and an arrival can preliminarily be estimated to be in the late hours of November 4, but this will be refined later as more data become available.
