Another CME From Sunspot AR1429

Another CME From Sunspot AR1429 -- Space Weather

Transiting the farside of the sun, never-say-die sunspot AR1429 erupted during the late hours of March 26th, producing its 11th major CME. The Solar and Heliospheric Observatory (SOHO) photographed the cloud flying over the sun's eastern limb.

According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the CME will hit two spacecraft, STEREO-B and Spitzer, on March 28th. Earth is not in the line of fire.

This event shows that AR1429, the source of several strong geomagnetic storms in early March, is still active. It will begin turning back toward our planet about a week from now. Stay tuned.

A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies.
