Coronagraph images from NASA's twin STEREO spacecraft show a coronal mass ejection (CME) emerging from the blast site and heading off in a direction just south of the sun-Earth line. The cloud could deliver a glancing blow to Earth's magnetic field sometime on Nov. 14th or 15th, sparking auroras.
Coronal Mass Ejections (CME) are amongst the most spectacular, transient phenomena taking place in the Sun. CME are colossal eruptions that happen periodically and during which enormous amounts of gas are released from the Sun into outer space.
The study of CME is particularly important in the context of 'space weather', since Earthward-directed CME have a strong impact on our planet's atmosphere, compressing the ionosphere and thus influencing satellites and telecommunications.
Check back for a refined predictions later today when SOHO images of the CME become available.
New sunspot 1123 in the Sun's southern hemisphere is crackling with C-class solar flares.
