STRONG FLARE, INCOMING CME: Departing sunspot AR1429 unleashed another strong flare on March 13th, an M7-class eruption that peaked around 1741 UT. Although the sunspot is no longer directly facing Earth, the blast will affect our planet. Analysts at the Goddard Space Weather Lab say a CME is en route to Earth, and its impact on March 15th at 06:20 UT (+/- 7 hours) could trigger minor to moderate geomagnetic storms
