A stunning eruption of filament plasma from the Sun this morning! This size of event can cause strong aurora activity if directed towards Earth, but alas – this one was not. #spaceweather

Here is a common sequence of auroral beads evolving into curls. This could be when the ballooning-mode instability is overtaken by some appreciable amount by Kelvin-Helmholtz instabilities. This can happen due to a magnetospheric driver in the nightside transition region.

A major eruption in AR 14168 associated with an M2.2 flare on 2025/08/10. This phenomenon, supra-arcade downflow, accompanies very energetic eruptions. The CME was not particularly spectacular in this case, though. Other M-class flares in the same region did not show this.
