Video link and Update via NASAs spaceweather FILAMENT ERUPTION, EARTH-DIRECTED: On Sept. 2nd, an enormous filament of dark plasma, which had been snaking across the face of the sun for days, became unstable and erupted. NASAs Solar Dynamics Observatory recorded the event (movies: #1, #2). A CME emerging from the blast site appears to have an Earth-directed component: According to NOAA analysts, the CME could deliver a glancing blow to Earths magnetic field on Sept. 6th. This is not a particularly fast or powerful CME. Nevertheless, the coming impact could spark auroras. The last two minor CMEs that struck Earth in late August triggered beautiful displays of Northern and Southern Lights. The reason: its aurora season. High-latitude sky watchers should prepare for Sept. 6th. spaceweather/images2014/03sep14/cme_anim.gif?PHPSESSID=qb3ccfgl74m7oog15ojulmh6b3 spaceweather/
