SOLSTICE GEOMAGNETIC STORM: A series of CMEs hit Earth’s magnetic field on June 22nd, producing a severe G4-class geomagnetic storm. Northern Lights spilled across the Canadian border into more than a dozen US states, including places as far south asColorado, Georgia, Virginia and Arkansas. “The auroras did not disappoint,” says Chris Cook, who witnessed the display from Cape Cod, Massachusetts:
“They were visible in deep twilight!” he adds. “I positioned myself on a beach overlooking Cape Cod Bay so I could capture the reflection in the water at low tide.”
More auroras are in the offing as Earth’s magnetic field reverberates from the CME strikes. NOAA forecasters estimate a 90% chance of polar geomagnetic storms on June 23rd, subsiding only a little to 70% on June 24th. Aurora alerts: text, voice
MEANWHILE … ANOTHER CME IS ON THE WAY:Big sunspot AR2371 erupted again on June 22nd (18:23 UT), producing a strong M6.5 class solar flare. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash:
X-ray and UV radiation from the flare ionized the upper layers of Earth’s atmosphere, causing a blackout of some shortwave radio signals over North America (blackout map). Mariners and ham radio operators, in particular, may have noticed disturbances at frequencies below ~20 MHz.
The explosion also hurled afull-haloCME directly toward Earth: movie. NOAA analysts are still modeling the storm cloud to estimate its likely time of arrival. Best guess: June 24th. Sky watchers should prepare for more geomagnetic atoms and auroras on Wednesday night. Solar flare alerts: text, voice
RT is as bad or worse than mainstream media. reading (watching/listening) that site is like trying to wade through a pond of treacle. designed to dumb you down as well. at least the english version.
