...and the june 7 CME compared to this one? ...do we have any data that say this one was bigger?

reply to post by ADEzor


It's difficult to say as we have no data on the density, velocity, temperature and such of the cloud.
A geomagnetic storms as in the Carrington Event 1859, today, would leave some big marks on our electronic infrastructure, disrupting electric power transmission, damaging transformers, radars, gps, satellites.
But it's just material world right, we would still be ok.

The CME on June 7th was sparked by a M2.5 class solar flare.

Today's largest flare is larger than the one yesterday, but it is ranked at C9.2....so far.

There was an M3.9 flare on October 2, 2011.

C = Low
M = Moderate

Yup.
Two weeks maybe.
Things could get interesting if it keeps up.

There you go again, Phage -- spreading fear and needlessly inciting the masses.

I didn't know that these days, interesting means fear.

...makes me think of ANON. what if they somehow know about this....[/tinfoiltheory] and use it to restart the whole system :-)
now THAT is what i call hope! :-D

Looks like the Sun has been burning its candle at both ends.

To many nights staying up late will do that to you.

There was nothing special with the June 7 CME.
The only thing is that there were 3 CME's that day, with different velocity.
The time it reached earth, one of the faster clouds joined another, hitting the geomagnetic field at the same time, which results in a K9, G5 storm.


Edit: I confused the dates, the one i'm talking about was the august 5 geomagnetic storm event.
The June 7 event was something beautiful yes. But didn't cause any major geo magn storms

that and the...

"Enormous ejection of particles into space shocks scientists."

Thanks for replies, deetermined and intergalactic fire.

I just remembered reading a Readers digest article about this scenario, some months back... I'll try to find it.. maybe it sheds some light about the question at hand.

It was about eight pages long and written in finnish so I don't know if theres a way confirming that source for you guys

scary stuff hopefully we don't get fried

You shouldn't connect, confuse solar flares with CME's.
Not all flares are followed by a cme and you can't determine the strength of a cme just by looking at the class of the flare.
A CME generated after an M9 flare can be stronger than one after an X9 flare, or there could also be no CME.
We have seen this many times in the past.
There is no real connection made, sometimes there is a cme after a flare, sometimes not.

So, a comet hit the sun last Sunday, October 2nd sparking the solar flare? This article says it sparked an "X" class flare, but the website I use showed it to be an "M3.9". Is information really being removed from the internet as stated in this article? Anyone know anything about this?

reply to post by Deetermined

The article is completely wrong.
The CME occurred on the far side of the sun. There is no way of knowing if there was a flare associated with it or its strength if there was one. The Earth will not be affected by it. No information was removed from the internet.

I believe you, especially since there was a M2.5 flare on the same day as the CME.

So, a comet did not hit the sun?

reply to post by Deetermined

A comet approached the Sun. Rather than hitting it, it's much more likely that it vaporized.

Isn't the comet's tail the evidence that it vaporized before hitting the sun?

reply to post by intergalactic fire

Good point.
A large and bright coma and tail from a very small nucleus would seem to indicate a very rapid loss of material.

"This amazing video from the SOHO mission (Solar and Heliospheric Observatory) shows a sun-diving comet hitting the solar surface on October 1, 2011 and unexpectedly a huge explosion occurs shortly after. Are the two events related? Probably not, but solar scientists don’t know for sure. The region where the CME originated was on the opposite side of the Sun from the comet hit, so that is very great distance. Scientists say there is no known mechanism for comets to trigger a CME."

"SpaceWeather.com reports that before 2011 most solar physicists would have discounted these two events as being related, but earlier this year, the Solar Dynamics Observatory (SDO) watched another sungrazer comet disintegrate in the Sun’s atmosphere, and it appeared to interact with plasma and magnetic fields in its surroundings as it fell apart. Could a puny comet cause a magnetic instability that might propagate and blossom into a impressive CME? Most likely this is just a coincidence, but this is definitely an event in which solar scientists are taking a closer look. The comet, named SOHO-2143, was just discovered on Sept. 30 by an amateur astronomer."

Yes.

They got it wrong. The video does not show the comet hitting the solar surface. It shows the comet disappearing behind the opaque disk of the coronograph.
