Last Gasp of a Big Solar Prominence

August 30, 2022 by Brian Ventrudo Filed Under: Solar System

Full-disk image of the Sun in H-alpha on August 30, 2022 at 15:57UTC.

The Sun kicked it into high gear this week! A few big prominences emerged, especially a towering tornado-shaped construct on the southern solar limb.
