Photographer and amateur astronomer Andy Casely posted a video of the solar ejection on his Twitter account
The video shows the plasma "rain" of the prominenceType I, which flows along the magnetic field lines at a speed of more than 50 km / s, Casey writes in a commentary on the video. A short time-lapse video shows 45 minutes of observations of the Sun. Each frame is a 15-second video shot at 130 frames per second.

Prominences are dense regions relativelycold compared to the solar corona plasma. In such structures, the matter that makes up the star is lifted and held above its surface by a magnetic field. For example, in this video, a prominence that formed near the north pole of the Sun rises to a height of about 165 thousand km above the surface of the star.
Astronomers distinguish three types of prominences.The rarest type is the first, it is he who is shown in the picture. It occurs when the material of the solar corona rises in a spiral to a great height. Retiring to a distance of about 100 thousand km, it breaks up: parts of the plasma break off the loop and fall along the magnetic field lines.
In addition to such prominences, the Sun alsocurved jets closed on the Sun (type II) are observed. Plasma bunches move along such jets along magnetic field lines. At the same time, their speed can reach up to 100 km / s. The third type is formations resembling a shrub or tree. Clots of matter in them move randomly and at relatively low speeds.
