The farewell greeting from 4274 finally reached Earth
The edge of the plasma cloud from the latest X4.0 explosion in region 4274 has finally reached Earth. At this point, the group of spots is no longer even visible on the solar disk (yesterday, the last spot was barely visible on the upper right edge of the Sun), so this is essentially a "dead hand signal." The center of six X-class flares, including the two most powerful events of the year, has disappeared from Earth's field of view on the far side of the Sun, perhaps never to return.
After the uninvited and somewhat illogical tears, which for some reason remain difficult to hold back, dry, and the surprise at this region's latest ability to accomplish the impossible (the plasma approached the planet from an unrealistic angle of 60 degrees) subsides somewhat, it will be noticeable that the impact is, for now, not particularly strong and feels more like a gentle farewell embrace than a final attempt to destroy what has so far failed to destroy. Noticeable magnetic field fluctuations with a slight increase in density, characteristic of the peripheral regions of plasma clouds, are observed in the vicinity of Earth. Plasma temperature and velocity have increased slightly; and that's about it for now. Geomagnetic indices are gradually increasing, but at the time of writing, they remained in the green zone. As always, there are less positive scenarios, suggesting that the main shock is yet to come, but since they contradict the general mood of mild sadness at parting, we resolutely reject them. However, time will tell.
The Sun, left behind by region 4274, looks unusually empty and dull. So, barring any unexpected events, the dead season is approaching—winter is coming not only to Earth, but to the Sun as well.
