[Regnum] Two powerful flares of the highest class occurred on the Sun. They were preceded by a series of medium explosions. This was reported by the Solar Astronomy Laboratory of IKI and ISTP.
“The continuous barrage of M-class flashes (level 4 on a 5-point scale) nevertheless led to the start of explosions of the highest level 5,” the laboratory’s website said.
Scientists reported that on August 5, two such events occurred on the Sun in a row. First, a flare of level X1.7 with a maximum at 16:40 Moscow time and lasting 30 minutes. And then a second event with a peak between 18:30 (Moscow time) and 18:50 (Moscow time). The preliminary rating of the second flare is X1.2.
It is specified that both explosions were recorded at the edge of the solar disk. In general, the Sun, apparently, is gradually entering a continuous activity mode, the laboratory added.
The Institute of Applied Geophysics reported that at 06:03 (Moscow time) on August 6, they registered an M1.2 flare lasting 18 minutes.
Solar flares are divided into five classes: A, B, C, M and X, depending on the power of X-ray radiation. The smallest class A0.0 corresponds to a radiation power of 10 nanowatts per square meter in Earth orbit, and when moving to the next letter, the power increases by 10 times.
As reported by the Regnum news agency, on the night of July 8, scientists registered five strong solar flares. Thus, one of them (flare M1.5) occurred at 00:59 Moscow time and lasted 10 minutes. At 02:23 Moscow time, a flare M1.0 occurred lasting 18 minutes. In the southern hemisphere on the eastern limb, scientists also registered flares M2.5, M1.1 and M1.3.
On June 16, the press service of the Solar Astronomy Laboratory reported the formation of a superspot on the Sun. Scientists warned that it could lead to strong magnetic storms on Earth.
