EARTH-DIRECTED CME: When the current spate of geomagnetic storms is over, another could follow close on its heels. A coronal mass ejection (CME), pictured below, is expected to deliver a glancing blow to Earth’s magnetic field late on June 30th or early on July 31st. The cloud was propelled in our direction during the early hours of June 28th when magnetic filaments around sunspot AR1777 erupted. The explosion registered approximately C4 on the Richter Scale of Solar Flares. Because the CME is not heading squarely toward Earth, there is still a chance that it will miss. Stay tuned for updates as the arrival time approaches. – Space Weather
