GEOMAGNETIC STORM: A dense cloud of plasma brushed against Earth's magnetic field on Saturday, June 8th, sparking a minor G1-class geomagnetic storm. The gaseous material may have been the flank of a slow-moving CME that left the sun on June 3rd. NOAA forecasters have issued a watch for more G1-class activity on June 9th as Earth's magnetic field continues to reverberate from the glancing blow. Visit Spaceweather.com for updates.
