Two strong solar flares occurred on Sunday.
The Sun enters the new week with increased activity. On Sunday, two consecutive significant flares were recorded, at M2.6 (peaking at 5:46 AM Moscow time) and M6.8 (late in the day, at 10:29 PM Moscow time). Both events are the strongest since June 3, or the last three weeks. In both cases, the flares were observed on the eastern edge of the Sun in the same growing sunspot group, No. 4473, which is currently moving from the far side of the Sun toward Earth. In fact, this is the only active center on the Sun currently. Of the seven flares recorded last Sunday, all seven occurred here.
At least one of the two flares (the first) was accompanied by an ejection of plasma into space, but it missed Earth and had relatively modest characteristics—speed and mass. These solar events are not yet a factor in space weather and are of interest primarily for scientific statistics. A group of sunspots will appear at the center of the solar disk, opposite the Earth, on June 25, just three days from now, but those three days still need to be lived through. Even this modest achievement doesn't seem guaranteed, and the surge in activity is considered localized. No one would be surprised if the Sun's energy ran out today.
