INCOMING CME, STORMS POSSIBLE ON EARTH DAY
Yesterday, April 18th, a magnetic filament attached to sunspot group AR2321 erupted, producing a C5-class solar flare. A movie from NASA's Solar Dynamics Observatory shows the filament splitting the sun's atmosphere as it hurtles away from the blast site.



Part of the escaping filament formed the core of a faint CME, which is now heading almost directly for Earth. The cloud should reach our planet during the late hours of April 21st. In combination with a solar wind stream already en route, the impact could spark geomagnetic storms around the poles on April 22nd, Earth Day.

This is a minor CME launched by a minor C-class flare, so it is natural to expect only minor storms when the CME arrives. That is probably what will happen. It is notable, however, that the intense geomagnetic storm of March 17, 2015, was triggered by a C-flare/CME combo only a little more intense than this one. The "St. Patrick's Day Storm" reminds us that any CME impact can produce a significant storm. Auroras for Earth Day, anyone?
