Inbound CME

Hrm. Wonder how far south the Aurora will come. I'm in Pennsylvania, and I've only ever seen it once, and even then it was a maybe-it-was, maybe-it-wasn't event.
 
No indication as to the polarity of this event? That is a very significant factor as I understand it.
 
Any word from NASA as to when we'll retaliate by sling-shotting the moon at the sun?

There is a large CME inbound, resulting from a flare and coronal eruption that occurred at 0300EST this morning. It is expected to reach Earth on Tuesday, Aug 3.

The ahead view of STEREO shows the event from the side. The sun's been a lot more active recently.

I loved this line from the article.....

"This sequence of events led to a huge magnetic bubble of plasma being blasted into space."

Oh the lengths that the mainstream will go to in an effort to avoid the dreaded term "electromagnetic", or "electric" anything. We have million plus mile per hour particles about to electrically light up the magnetosphere, and yet it's just a "magnetic bubble". What BS.

Oh the lengths that reporters will go to make things simple for their readers. They will even not mention the dreaded term "electromagnetic", or "electric" anything. They do not even explain the basic fact that a moving magnetic field has a corresponding electric field. They leave it up to the readers to know this :jaw-dropp!

ETA:
One more time MM - Astronomers use the terms electromagnetic and electric a lot in their published papers. There are not as many papers emphasizing the electric part of electromagnetism for the simple reason that magnetic fields are easier to observe (astronomy has a lot of observation in it). Astronomers of course know that given a magnetic field the electric field can be found.

What resumed phobia is being mentioned here? AFAIK, most people understand electricity a lot more than they understand magnetism, and especially the connection between them. Now, if you'd said something about scientists not wanting to hear about elecrical comets or some such, I can imagine that (though not understand that, and the reporters are probably snowed in that entire area of argument).

Fear of all things "electrical" in space!

Well, the connection between them is *electrical* in nature. The current flowing in/through the plasma creates the magnetic fields we see in the light plasma. They went out of their way to *NOT* mention that part of the process.

There is no such thing as "magnetism" without current flow inside of light atmospheric plasmas. There's nothing "magnetic" about any of these events, they are "electromagnetic" events, particularly since these are discussing charged particles that are moving at well over a million miles an hour. The term "magnetism" or "magnetic" appears lots of times in that article, yet not a single mention whatsoever of the *ELECTRICAL CURRENT* that produces those magnetic fields. Hmm. Are they electrically phobic or what?

Oh boloney. You guys go *OUT OF YOUR WAY* to dumb down the process. Every article, every paper dumbs down the process and ignores the electrical current *ENTIRELY* or treats it as a secondary "effect" of some magnetic phenomenon. The reporters are innocent victims like the rest of us.

ETA2: WHo is "You guys"? I have never written a news article or scientific paper about astronomy.

Every astronomy paper does what all scientific papers do - they assume that the person reading them has at least a rudimentary knowledge of science and thus knows that magnetic and electric fields go together.


Of course they ignore electric current when electric current has nothing to do with the subject of the paper.
  • If they are discussing the magnetic field of the Earth then electric currents are usually not mentioned.
  • If they are discussing coronal loops
    Coronal loops form the basic structure of the lower corona and transition region of the Sun. These highly structured and elegant loops are a direct consequence of the twisted solar magnetic flux within the solar body.

    then they do not usually mention electric currents.
  • When they discuss magnetic reconnection, then currents become more important.
  • When they discuss Birkeland currents in the Earth's magbetosphere, then magnetism hardly gets a mention.
And yet another time, MM:
Astronomers use the terms electromagnetic and electric a lot in their published papers. There are not as many papers emphasizing the electric part of electromagnetism for the simple reason that magnetic fields are easier to observe (astronomy has a lot of observation in it). Astronomers of course know that given a magnetic field the electric field can be found.

Electric fields are not a secondary "effect" . No scientist thinks of them as such. That is why there is such a thing as electromagnetism. Electric fields are as primary an effect as magnetic fields but harder to observe.

ETA
Getting back to the OP rather then your personal prejudice about astronomy papers:
This is a news story based on a press release. So of course it is going to be dumbed down. Even the quote you are so enraged about is a bit too dumb - "This sequence of events led to a huge magnetic bubble of plasma being blasted into space" since there is no "magnetic bubble" involved.

And then you go off the rails about this bit of simplication

MM: What do you think the word plasma in the quote means?

To me it means million plus mile per hour particles about to electrically light up the magnetosphere.

a) For a response, please see any of the half-dozen threads where you've made that statement and gotten responses. Has something changed since then?

b) (blather, rinse, and around we go again: ) Nor do they mention the magnetic vector potential that produces the magnetic field.

If you're reading some engineering plans, and the plans report the base and height of several right triangles, does that mean the engineer is AFRAID of hypotenuses? Does it mean that the engineer thinks the hypotenuse isn't there? No, it means the base and height are easier to measure and that there's a convention for how to describe them.
 
What's more disruptive: a C-class flare, or an attempted Mozina thread hijack?

My money's on the latter.

Why thank you. :)

Just for that I'll throw you a bone and resist hijacking the thread. :)

This presentation of the Ace data is very cool IMO and shows the effects of the solar wind on the magnetosphere. So far it's been pretty boring, but things should pick up later in the day.

A few weeks ago we had a significant jump in the density numbers. In a few minutes it jumped from about 5 to 35 p/cc for about an hour. A few days later the solar wind velocity doubled for a while. I frankly didn't personally see any visual correlation to events seen in 195A in any satellite images which is why I found it rather "unusual" from my perspective. It will be interesting to see how this particular CME compares to events from the past few weeks in terms of intensity as measured by density and velocity. The sun is definitely becoming more active.
