Summary: Twisted magnetic fields above giant sunspot 30 erupted on Monday, July 15th, at 2005 UT. The explosion sparked a powerful X3-class solar flare and hurled a coronal mass ejection (CME) into space. Although the CME was not squarely Earth-directed, it nevertheless buffeted our planet's magnetic field on July 17th and triggered modest geomagnetic activity.
