Our Sun: Earth directed CME to arrive on the 30th

C-Class solar flare that produced earth directed CME UPDATE: As pretty as it was, the CME has come and gone with not som much as a larger footprint for the northern lights today.  As we said, only a c-class solar flare,  not that big in the first place but was directed at earth.

A CME (coronal mass ejection) was released today from what looks to be sunspot 1330.  The Solar flare that produced this CME was a C-Class in size measured at 2.6.  Although not a huge solar flare by the standards of solar flares, the CME is going to hit the earth very hard and should last approx 11 hours.   This coronal mass ejection should not cause much of a disruption on earth but should provide another opportunity to see the auroras in the mid to upper US states.

 

Arrival of the CME on October 30thCoronal mass ejections release huge quantities of matter and electromagnetic radiation into space above the sun’s surface, either near the corona (sometimes called a solar prominence) or farther into the planet system or beyond (interplanetary CME). The ejected material is a plasma consisting primarily of electrons and protons, but may contain small quantities of heavier elements such as helium, oxygen, and even iron. It is associated with enormous changes and disturbances in the coronal magnetic field.
