British scientists have discovered Alvenov waves warming the Sun's corona

The researchers were able to record Alvenov waves warming the Sun's corona to ultra-high temperatures. This was announced on October 24 on the website of the press service of the British University of Northumbria.

"We have finally been able to directly see these "swirling" fluctuations that periodically cause magnetic field lines to penetrate into the corona and leave its limits," explained Professor Richard Morton.

It is clarified that this discovery was the end result of a very long and painstaking search that began back in the 1940s.

According to many theorists, Alvenov waves are the cause of a sharp temperature transition between the upper layer of the Sun's surface — the photosphere (5.8 thousand kelvin) and the corona (about 1 million kelvin). Their existence was predicted by the Swedish physicist Hannes Alven in 1942.

Earlier, on October 18, the Laboratory of Solar Astronomy at the Space Research Institute of the Russian Academy of Sciences reported that six flares, two of which turned out to be quite strong, were recorded on the night of October 18. According to the researchers, four weak outbreaks were recorded before midnight.
