Another Major Flare

Big sunspot AR1429 has unleashed another major flare--an X5-class eruption on March 7th at 00:28 UT.

As a result of the blast, a radiation storm is underway and a CME will likely hit Earth's magnetic field in a day or so.
Geomagnetic storms are already in progress at high latitudes due to earlier eruptions from the active sunspot.
Last night, auroras were spotted over several northern-tier US states including Michigan and Wisconsin.
