A solar
flare of the penultimate power class was recorded on the morning of June 2, the
Institute of Applied Geophysics (FSBI "IPG") told TASS.
"On
June 2, at 07:45 Moscow time, an M1.2 (S22E89) flash lasting 5 minutes was
registered in the X-ray range," the report says.
Solar
flares, depending on the X-ray power, are divided into five classes: A, B, C, M
and X. The minimum class A0.0 corresponds to the radiation power in Earth orbit
of 10 nanowatts per square meter. When moving to the next letter, the power
increases 10 times. Flares can be accompanied by solar plasma emissions, the
clouds of which, reaching the Earth, can provoke magnetic storms. tass.ru.
