Geomagnetic Storm

[Oubaas]

Well, the NOAA has set condition G4. There's a sun spot that's fifteen times wider than the Earth and growing. We're approaching Solar Maximum. There have been three major Coronal Mass Ejections of late, and the emissions from those CMEs will be reaching Earth starting this evening. The Aurora Borealis will be visible in much of the northern hemisphere, and the Aurora Australis will be visible in the southern hemisphere.

We could be headed for a Carrington Event like the one that occurred in 1859, when telegraph offices caught fire across the country. Only now we're dependent on cell phones, computers, GPS and other satellite services, motor vehicles full of electronics, aircraft, and the electrical grid. So the impact of such an event would be significantly more intense than it was in 1859. You could kiss all that stuff goodbye.

It's possible that tonight we're going to party like it's 1699. Nobody really knows what to expect. Imagine what it would be like in major cities if tonight everything that uses electricity burst into flames. No power. No vehicles, No police or EMS. No cell phones. No computers. No GPS. Etcetera. I'm glad that I live out in the middle of nowhere and have horses.

Anyway, tonight's the night. There's your doom porn for the day.

Supposed to hit today and into early Saturday. I think another CME was behind this one but not sure if we’re in the path of it. Should be a fairly active Aurora Borealis

Just got an alert: “CME IMPACT IMMENENT…”. Two more on the way. Earth will be messy during the next 5 days or so with geomagnetic storms conditions up to severe G4 geomagnetic storm level expected.

Coronal mass ejection impact imminent

The first of the anticipated coronal mass ejections has arrived at STEREO Ahead, a satellite slightly closer to the Sun than DSCOVR. The impact has been significant there with a maximum interplanetary magnetic field Bt value of 41nT and a minimum Bz value of -33nT at the time of writing. If we see similar values at Earth (which we should) this is certainly going to cause a significant geomagnetic storm where severe G4 geomagnetic storm conditions (Kp8) are absolutely possible! Charge your camera batteries and keep an eye on the data right here on the SpaceWeatherLive website or download our app from your Android or iOS store. This could become one of the strongest geomagnetic storms of this Solar Cycle with aurora visible from many locations in central Europe this evening!

Two more earth-directed coronal mass ejections

Sunspot region 3664 continues its old trick today of being a major flare producer. Since our news article yesterday it produced two more eruptive X-class events. One being the X1.1 event mentioned at the end of yesterday's news article and today's largest event thus far was an eruptive X3.9 solar flare which peaked at 06:53 UTC. Both of these events were eruptive and launched asymmetrical halo coronal mass ejections into space which also have an earth-directed component. Due to the location of sunspot region 3664, the bulk of these CMEs are directed towards the south-west but we do expect these to arrive at Earth as well.

That means there are now six, yes six, coronal mass ejections that have a good chance to pass our planet in the days ahead. It will likely be impossible to tell them apart but space weather at Earth is going to be messy during the next 5 days or so with geomagnetic storm conditions up to the severe G4 geomagnetic storm level expected.

Soon this MASSIVE CORONAL HOLE will be looking directly at earth and we will face the possibility of being wacked by the biggest Coronal Mass Ejection in the history of man and sent back to the Stone Age.

The image from 3 Nov. on the left and 1 Dec on the right. It has filled in a little in the south but extended and widened to the north. How long will it last? It is already 6 months old.
