A class M flare occurred on the Sun on the morning of February 11. This was reported by the Institute of Applied Geophysics (IPG).
At 08:35 Moscow time, an M1.6 flare was recorded in the X-ray range in group of spots 3981 (N06W88), which lasted 25 minutes.
The Laboratory of Solar Astronomy of the IKI and ISZF recorded four solar flares of class C and higher. There have been no magnetic storms in the last 24 hours. The state of the magnetosphere remains calm so far.
Solar flares are divided into five classes depending on their power: A, B, C, M, and X. A class A0.0 flare emits 10 nanowatts per square meter in Earth's orbit. With each subsequent letter, the power increases by a factor of 10. Flares are often accompanied by ejections of solar plasma, which, when reaching Earth, can cause magnetic storms.
Previously, five flares of the penultimate power level were recorded on the Sun. The first of them occurred on February 7 at 02:27 Moscow time in the X-ray range in the group of spots 3984 (N12W35). Three flares with powers of M1.6, M1.1 and M3.2 were recorded in the active center 3981. The last flare turned out to be the strongest, receiving a score of M7.6.
