Large filament eruption to deliver a glancing blow early Friday
A large solar filament located in the southern hemisphere lifted off the Sun at about 8:50 UTC on August 20, 2013. A bright Coronal Mass Ejection (CME) was produced as the result. Though the majority of Sun's material is directed south current forecast shows it will make a glancing blow to Earth's geomagnetic field early on Friday, August 23, 2013.
Wide spread geomagnetic storming is not expected but high-latitude skywatchers should be alert for auroras.
