"A HYPERACTIVE SUNSPOT: New sunspot AR3372 is seething with activity. In the last 24 hours alone it has produced eight M-class solar flares (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 July 11th. In addition, episodes of sudden ionization in the atmosphere are doppler-shifting the frequency of time-standard radio stations such as Canada's CHU and America's WWV (data).
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. "
