On Sunday, March 30, four flares occurred on the Sun. Three of them were classified as M-class flares — the second most powerful in the X-ray range.
The first M1.4 flare was recorded at 00:38 Moscow time in the solar spot group 4048 (S14E8). Its duration was 33 minutes. At 2:00, instruments recorded a second, stronger flare, class M1.9, which lasted 38 minutes. The third M1.5 class flare occurred at 4:48 in the S14E8 spot group. Its duration was 45 minutes.
Another, weaker flare was recorded at 7:30. It lasted 14 minutes. Scientists classified it as a C-class.
Magnetic storms are not expected in the next 24 hours.
Depending on the level of X-ray radiation, solar flares are divided into five categories: A, B, C, M, and X. Category X flares are the most powerful of all. Category M flares are considered to be of medium strength. They cause radio interference on the daytime side of the Earth and can sometimes lead to magnetic storms and a solar radiation storm — a potentially dangerous phenomenon caused by streams of protons and ions.
Previously, nine powerful flares were recorded on the Sun. Disturbances on the Sun began on March 26 at 02:15 Moscow time, peaked at 02:24 and ended at 02:35.
