A giant prominence broke off from the Sun.
On the night of October 13–14 a giant prominence — a plasma filament — detached from the surface of the star and was observed for several days by specialists from the Space Research Institute and the Institute of Solar-Terrestrial Physics of the Russian Academy of Sciences. According to the Laboratory of Solar Astronomy, the ejection was so large that it could be seen even with amateur telescopes. As scientists noted, prominences of this size are always expelled by the Sun into space, since it is the only way for the star to rid itself of a structure of that magnitude. Experts clarified that the trajectory of the ejected plasma stream passes between Earth and Mercury, without affecting either planet. It was a fortunate coincidence: had the ejection occurred later, the wave could have hit Earth, causing powerful geomagnetic storms similar to those recorded on June 1 of this year, reports RBC. The plasma filament has now moved about 20 million kilometers away from the Sun and continues its journey into space.
