Solar wind density

[Yak]

Why is the solar wind density so high?

[Solarflaretracker200]

I was wondering the same thing. I think that’s the highest I’ve ever seen it go.

All indications are that a transient feature, likely one of the CMEs from 23 Sep, was passing by the DSCOVR spacecraft.

From SWPC

Maybe a mix of a southern CH CIR and weak center disk filament eruption early morning on the 22nd

This certainly screams CME to me, interesting! G2 already!

NOAA/SWPC has issued a Strong (Kp=7) Geomagnetic Storm Warning until 27/0900Z due to effects from a coronal mass ejection.

Don't ever recall seeing density going to 90 before either.

 

I'm liking that 18nT IMF strength tho. That's some G3 potential right there!

[Isatsuki San]

if that was a touch of a cme, who is held by epam?

[Solarflaretracker200]

What did this CME take? Steroids to get a G2 so fast?

[LunarLights58]

There was a CME?

¿Qué se llevó este CME ? ¿Esteroides para conseguir un G2 tan rápido?

the density at 90 and the bz 15 at south, it helped a lot to the fast g2,

[Xavier Stanton]

I will say, densities have gotten much higher before. On March 31, 2001, for a short period of time, the solar wind density was, for a short time, over 150.

Oh I see

what do you mean?

[CMEHunter]

The Hemispheric Power is amazingly low for a Kp 6 with this density and IMF strength! The solar wind speed is coming up, but the Bz just needs to flip south🤞

nothing, I forgot how it worked, the epam, I wanted to say that the epam was detected, if it was another cme, but no, I missed

It is the first time that I see the Interplanetary Magnetic Field bt at 30

[Sam Warfel]

Same, I’m not sure I’ve ever seen a Bz of 30 before… if only it would flip south…

when it’s actually night it does nothing lol.

Same. This is absolutely mind blowing. Even during multiple G3s in the past, and that one St.Patricks day event several years ago, it never got this high. 

 

If the IMF ever goes south, we will get G3 very quickly and maybe even touch G4!

[MinYoongi]

is there a reason density dropped when the BZ rose? some form of transient´?

[Solarflaretracker200]

OK THIS NEEDS TO TURN SOUTH. COME ON.

What would that do?

[Solarflaretracker200]

IMF IS 28. WTF. that’s the highest I’ve ever seen that. 

[MinYoongi]

Its the highest value in like 5 years. cool.  

I still wonder if its a CME or CH HSS. Or both. @Orneno, do you have a guess? 

also, taking pictures?

That would be Aurora time. Especially if a KP7 happens. Then frick sleep and I’ll go try and see northern lights.

Wait for real? Damn.

Yeah, that bz is being bs
