Northern Lights Possible Over Wyoming Tonight And Tomorrow Night
According to spaceweather.com, a series of CMEs, or coronal mass ejections, 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 as Colorado, Georgia, Virginia and Arkansas.
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.
