The sun released 2 massive, nearly simultaneous ropes of solar plasma earlier today (around 8:40 UTC on January 20). Both are in the east, one from the eastern limb and the other just to the west of it, on the solar disk. Both giant ropes of sun stuff are called "erupting filaments." But - because of its location - we typically call the one on the solar limb (edge) an erupting PROMINENCE. Prominences and filaments are the same thing! But we see them differently. And so this different naming is historical. At one time, scientists thought these 2 type of events WERE different. Now, we realize we just see them from different perspectives. But the name prominence stuck. Now, it just means "a filament seen on the limb with space behind it." Neither eruption had a notable flare associated with it. But both produced coronal mass ejections, or CMEs. Given their locations, the CMEs most likely don't have Earth-directed components. But more imagery is needed to make a more confident determination.
