Spaceweather.com: GEOMAGNETIC STORM WATCH (G1)
GEOMAGNETIC STORM WATCH (G1): NOAA and NASA analysts agree: A CME will hit Earth’s magnetic field on July 14th or 15th. The glancing blow could spark minor G1-class geomagnetic storms with high-latitude auroras. The CME was hurled into space on July 11th by an erupting magnetic filament in the sun’s southern hemisphere. Aurora alerts: SMS Text
A HYPERACTIVE SUNSPOT: New sunspot AR3372 is seething with activity. Since it first appeared on July 11th, the sunspot has produced eight M-class solar flares, three of them quite strong: graph. To the extreme ultraviolet telescopes onboard NASA’s Solar Dynamics Observatory, it looks like the northeastern limb of the sun is on fire:
The rat-a-tat-tat of solar flares from AR3372 is causing a rolling series of shortwave radio blackouts around all longitudes of our planet. Ham radio operators, mariners and aviators may have noticed loss of signal below 30 MHz on multiple occasions since the sunspot appeared.
If current trends continue, we should expect more strong M-class flares during the next 24 hours with a chance of X-flares as well. This sunspot will become even more geoeffective in the days ahead as it continues to turn toward Earth. Solar flare alerts: SMS Text
