SOLSTICE SOLAR FLARE:

The first day of northern summer began with a solar flare. Magnetic fields above sunspot complex 1236 erupted during the early hours of June 21st, hurling a coronal mass ejection (CME) almost directly toward Earth.  The incoming CME does not appear to be particularly potent; nevertheless, the cloud could trigger polar geomagnetic storms when it reaches Earth on or about June 23rd.
