On October 15 at 07:15 Moscow time, an M4.8 flare with a duration of 43 minutes was registered in the X-ray range in a group of spots, according to the Institute of Applied Geophysics. This is the second strongest event in the last 4 months.
Today, records will be broken - so far, two- to three-month records. It is expected that the X-flare level may be reached for the first time since the beginning of summer.
A high level of geomagnetic disturbance was also confirmed at the Laboratory of Solar Astronomy of the IKI RAN.
Currently, a significant increase in activity is observed on the Sun, as predicted yesterday. The graphs show a continuous increase in the background radiation of the Sun, which has increased 4 times in a day. Flare solar activity is mainly moderate, with possible class X flares, including proton flares. In other words, the Sun is currently forming fluxes of X-ray radiation at the level of strong flares even in the absence of explosions.
It should be noted that class X flares are the most powerful flares, capable of causing long-term communication disruptions and overloads in power grids, especially in northern latitudes. In this regard, experts note that conditions for shortwave radio communications may deteriorate in the coming days.
Earlier, www1.ru wrote that an "inadequate" size protuberance formed on the Sun.
