Major solar flare March 7

The following is from

SOLAR ACTIVITY: 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.  Check for updates and images.
