Message Subject PARKER SPIRAL Connects a Back Sided Plasma Cloud Erupting from Sun to Earth in a Rare Solar Event
Poster Handle Anonymous Coward
Post Content
This post comes from another thread, Thread: Rare Space Weather Event ! but the OP never came back on. So, I'm going to post it again, with an explanation of this rare and incredible solar event.

There was a Coronal Mass Ejection ON THE OTHER SIDE OF THE SUN THAT HAS MAGNETICALLY CONNECTED WITH THE EARTH.

Below is a warning that was issued due to proton flux increases.


PRESTO ALERT

Fast warning for important solar events with implications for the space environment. Source SIDC (RWC-Belgium)
Frequency ASAP, when needed.

The proton flux measured by GOES13 increased this morning. The storm threshold is not reached. We don't expect the threshold to be passed.
A back sided plasma cloud came into view of STEREO B COR2 at 02:54UT, March 21, 2011. This CME is probably associated with the increased proton levels. The Earth is magnetically connected with the source site behind the Sun. The Parker spiral has bended magnetic field lines that guide the electrically charged protons. The Earth is near such field lines along which these protons travel. This is a rare event.

So, this is what all that means, and I even put a pretty picture in the explanation so it is a little easier to visualize how a CME can erupt on the back-side of the sun, and still effect Earth. IMO, that is absolutely amazing!

They are talking about the Parker Spiral.

The spiral shape is similar to the pattern produced by a spinning lawn sprinkler, for similar reasons: the solar wind travels outward from the Sun at a uniform rate, but an individual jet of solar wind from a particular feature on the Sun's surface rotates with the solar rotation, making a spiral pattern in space. Unlike the jet from a sprinkler, the solar wind is tied to the magnetic field by MHD effects, so that magnetic field lines are tied to the material in the jet and take on an arithmetic spiral shape.

Here's a picture of it...

:parkerspiral:

See how the magnetic field lines actually look like a 'spinning wave' being emitted from the sun. Well, to be technical, the shape is this: Unlike the familiar shape of the field from a bar magnet, the Sun's extended field is twisted into an arithmetic spiral by the magnetohydrodynamic influence of the solar wind.

So, the CME exploded on the other side of the sun, and it gets caught up in the magnetic wave of the Parker Spiral, pulling the CME around the curve of the sun. You can imagine it with the picture above...the CME following the Parker Spiral around. Well, as it is doing it, it comes in contact with Earth's magnetic field, and pulls it in Earth's direction...

Pretty fucking cool!
