Coronagraph images on the morning of November 12 from the Solar and Heliospheric Observatory (SOHO) and NASA’s twin STEREO spacecraft show a weak mass ejection emerging from the sunspots 1123 heading off in a direction just south of the sun-Earth line. The coronal mass ejection is expected to graze the Earth’s magnetic field sometime on Nov. 14th or 15th. High altitude observers may expect a nice aurora show those days.
As the solar cycle matures, we may expect an increase of this type of activity over the next few years
