It looks like this one. The speed is estimated in ranges of ~410-460 km/s, which is very slow. Unless it somehow carries some magnetic field of 30+ nT and gets nicely constantly southward, I do not think it will be significant for anybody else than just strictly high latitudes. I do not think I ever saw a significant impact from any CME that was slower than 550 km/s, though my memory is not the best.

Last year there was a CME at about 450km/s that caused a G3, but I don't remember exactly when that was. But there was an eruption of filaments that was clearly visible and the characteristics were good. And from this one I'm more than sure we shouldn't expect anything special.

The C6 last night around 22:00 does eject something but looking at the past 24 hours of LASCO data shows that its not a lot and rather slow to be of great interest I think .

thank you :) I was interested because next week I'm in the arctic, so any CME is welcomed for me hehe

What are you doing in there?

looks like another halo CME

Usually such eruptions don't have a full halo, so I can say that it's very likely to fly past the ground, and if it does hit tangentially, the impact will be weak. If it were a massive eruption, it would have a better chance.

We're chasing the northern lights in Tromso, we've been three times already and had awful luck with weather, be it space weather or earth weather 😅 just trying to figure out what I can expect and reasonably prepare for haha

Bring lots of coffee!! Haha. Good luck!!!

The next few days look very bad with weather there, but all best luck. If the skies get clear, there is almost no chance for no auroras there.

I don't think these dimming events from today and yesterday will create an earth directed component but Solar demon does show quite a bit of dimming from one event close to the east limb and another on the west limb region.

I’m gonna keep one eye on Kiruna anyway and the other on the weather forecast for Eastern Washington state until the weekend. Even with wind speeds above 700, it still gives me just enough time to race over the pass with my go kit of binoculars, tripod thermos of coffee and this silly iphone. 😎

Spaceweather.com calls for a G1 on the 20th, referring to this NASA model:

This seems different than what we have here on SWL (?) BTW, how do you pace an animated GIF? It is so hard to see the timing in these fast animated GIFs from NASA.

You could open it in a video editing program

Spaceweather.com預測 20 日將出現 G1，參考NASA 的以下模型：

這似乎與我們在SWL上看到的不同(?) 順便問一下，您如何調整動畫 GIF 的節奏？在美國太空總署 (NASA ) 的這些快速動畫 GIF 中，很難看清時間。

https://ezgif.com/speed offers a possibility to upload a GIF (or provide it from an URL) and set a custom speed. There is a preview, so you can see it almost instantaneously.

I can guess but perhaps @Jesterface23 is still around for his take on the confusion all too typical with CME predictions.

That's what I do if I need to take a closer look.

Not sure why NASA doesn't do it like SWPC, though, so you can start/stop/scrub as you need to.
