Streaming Prominence

Streaming Prominence

Streaming Prominence

A prominence at the edge of the Sun provided us with a splendid view of solar plasma as it churned and streamed over less than one day (June 25-26, 2017). The charged particles of plasma were being manipulated by strong magnetic forces. When viewed in this wavelength of extreme ultraviolet light, we can trace the movements of the particles. Such occurrences are fairly common but much easier to see when they are near the Suns edge. For a sense of scale, the arch of prominence in the still image has risen up several times the size of Earth.

Hedgerow Prominence

Hedgerow Prominence

Hedgerow Prominence

A solar prominence at the suns edge put on quite a display of plasma being pushed and pulled by unstable magnetic fields (May 22-24, 2017). We call them hedgerow prominences because they look somewhat like a hedge of bushes. This is one of the better examples of this type of solar phenomenon than any we have seen in quite some time.
