A solar flare of the penultimate power class M1.1 was recorded on October 20. This was reported by the press service of the "Institute of Applied Geophysics named after Academician E. K. Fedorov" (FSBI "IPG").
At 08:27 Moscow time, an M1.1 class flare with a duration of 34 minutes was recorded in the X-ray range in group of spots 4248 (N03W89).
The Laboratory of Solar Astronomy of the IKI and ISZF also reported that the geomagnetic situation on Earth has stabilized.
At the moment, the risks of large flares affecting the Earth are zero; in fact, they became so 2-3 days ago. The pressure from the coronal hole, which prolonged the period of storms, has also been almost completely removed at the moment.
In the next 5-7 days, there are no factors on the Sun that could disrupt the geomagnetic situation. A prolonged calm is expected.
