Just letting you know. A fast CME incoming at midnight UTC. G3-class geomagnetic storm is in progress on June 22nd after a series of CMEs hit Earth's
magnetic field. Sunspot AR2371 with 'beta-gamma-delta' magnetic field compexity that harbors energy at approximately 20% chance for X-class solar
flares.
oops. fixed.
btw. the mass arrives in just two days after a flare so it's a fast one and after our magnetosphere got a couple of preshock punches I expect a
G5-class geomagnetic storm even if it was not that big. It's G4 already. People will go mad anyway as usually. Energy is coming. It was a bit lazy
lately with just those pesky negative polarity coronal holes.

The way that event is described, it sounds like something that would require that you stock up on food and water and seek shelter at least 1000 meters
underground. But I guess in reality, at most there will just be pretty lights in the sky.

Something like that. Anyway I'll be on the lookout for auroras, meanwhile big geomagnetic storms had been predicted for the current solar cycle 24
since 2008, after observations made in 2007. The reasons explained here,
A snippet,
"Dec. 16, 2008: NASA's five THEMIS spacecraft have discovered a breach in Earth's magnetic field ten times larger than anything previously thought to
exist. Solar wind can flow in through the opening to "load up" the magnetosphere for powerful geomagnetic storms. But the breach itself is not the
biggest surprise. Researchers are even more amazed at the strange and unexpected way it forms, overturning long-held ideas of space physics.
"At first I didn't believe it," says THEMIS project scientist David Sibeck of the Goddard Space Flight Center. "This finding fundamentally alters our
understanding of the solar wind-magnetosphere interaction."
The magnetosphere is a bubble of magnetism that surrounds Earth and protects us from solar wind. Exploring the bubble is a key goal of the THEMIS
mission, launched in February 2007. The big discovery came on June 3, 2007"
Of course. Everyone here knows what an X-Class flare is and relax. Just ignore my enthusiasm and enjoy the sources which are calm as ever.
The reason I actually post the update are the connections I like to share and talk about right here from time to time.
According to the aurora forecast it is kp7. The aurora institute site says Portland, Lincoln neb. And NYC could see it overhead. Additionally as far
south as Reno could see it on the horizon.
I'm in SW Washington and I'm going to check it out in about an hour. That's when it should be dark.

Kp index 8. Wow. It's like the systems over Europe have reacted on the solar wind and made the Earth-winds stronger.
I like the "Earthspot" theory. The next shock wave will come on thursday morning
Here's the update if you haven't checked it yet.
I know there are always strong lows and winds somewhere in the world but I could swear the wind here in Europe reacts on the solar wind precisely
The fifth shockwave from the M7.9 is on the way. It's the largest flare yet from this Sunspot but a slower one. The proton density will be higher for
sure. It will impact tomorrow.
I think I've seen far worse and I don't remember the satellite internal charging and radiation storm stopping the air traffic with Kp9 and
magnetometer off the scale. Interresting.
The Earth's magnetosphere has to be pretty weak or such a combo is worse than a single X-class

Hmm, it's been here pretty quickly. Fast but actually not dense at all. The density is increasing as the speed goes down. No proton surge or electron
dropping and the shield is doing just fine.
Situation is over. It was a nice show. Thank you for your attention and contributions
