It took a little while but there is finally enough SOHO LASCO coronagraph imagery to analyse the coronal mass ejection that was released during yesterday's M3.9 solar flare from sunspot region 2449. A partial halo coronal mass ejection was launched and a glancing blow might arrive at Earth.
For more information regarding that event please visit our news article from yesterday.

SOHO/LASCO shows us a partial halo coronal mass ejection which can be seen leaving the Sun at a speed of about 650km/s. The bulk of this coronal mass ejection is directed well south and east from Earth. We expect a minor glancing blow at most either late tomorrow (UTC timezone) or early on Thursday 12 November. We do not say this too often but NOAA's ENLIL solar wind model looks fairly accurate compared to with what we have in mind. Active geomagnetic conditions (Kp4) are expected from this event with a minor chance for an isolated period where we could reach the minor G1 (Kp5) geomagnetic storm threshold.
