Sanjana Greenhill sends this picture from Anchorage of a geomagnetic storm and bright auroras over Canada and Alaska
As predicted, a solar wind stream hit Earth’s magnetic field during the early hours of Aug. 23rd.
“The whole sky was lit up,” says Greenhill. “Pictures barely do any justice to what the eyes saw.”
More storms could be in the offing. Minor CMEs that left the sun on Aug. 21st and 22nd are expected to sideswipe Earth’s magnetic field on Aug. 24th. NOAA forecasters estimate a 70% chance of polar geomagnetic storms when the CMEs arrive. Aurora alerts: text or voice
