[João Costa > CT1FBF]

Earth enters solar wind stream

A G1-class geomagnetic storm is in progress on April 12th as Earth
enters a stream of fast-moving solar wind.

NOAA forecasters estimate a 70% chance of additional storming on April
13th as Earth moves deeper into the stream. Also, a minor CME from big
sunspot AR2529 could deliver a glancing blow to Earth's magnetic field
on April 13th, further boosting the odds of storminess.
