A solar eruption that would not quit.
In this H-alpha time-lapse I took yesterday, plasma repeatedly surges upward from the same active-region footpoint on the edge of the Sun. Each burst follows magnetic field lines, fades, and is followed by another surge.
These structures can extend tens of thousands of kilometers above the solar limb — far larger than Earth — yet they can change in just minutes. This one reached over 100,000 km.
It may look like flame, but it is not fire. This is super-heated ionized hydrogen being guided and accelerated along magnetic field lines above the Sun.
Look closely – did you notice the adjacent smaller surges too?
