Observation of Strong Solar Flares

Experts from the heliophysics department at the Institute of Applied Geophysics in Moscow announced that they observed two strong flares on the Sun yesterday, Monday. The institute's statement indicated: "Experts detected an M1.4 flare (S12E89) at 6:37 AM Moscow time, lasting for 21 minutes, and another M1.1 flare (S12E81) at 3:14 PM, which lasted for 12 minutes. These flares were accompanied by disturbances in high-frequency wireless communications." According to space weather observations, the impact of X-ray solar flares on the ionosphere is measured on a scale of five levels, with R5 being severe and R1 being mild. Currently, R1 is the predominant level, thus low-frequency wireless communication disturbances are noted, affecting the positioning of ships and aircraft. It is noteworthy that in April 2023, the strongest flare on the Sun, classified as M1.7 / 2N, was observed, along with a coronal mass ejection toward Earth at a speed of 1,100 kilometers per second, leading to the occurrence of a significant geomagnetic storm on Earth.
