The Sun blew out a coronal mass ejection along with part of a solar filament over a three-hour period on Feb. 24, 2015. While some of the strands fell back into the Sun, a substantial part raced into space in a bright cloud of particles (as observed by the NASA-ESA Solar and Heliospheric Observatory spacecraft). Because this occurred way over near the edge of the Sun, it was unlikely to have any effect on Earth.
