Hinode's Solar Images vs. Birkeland's Terella?

[MGmirkin]

Well, I've given up on my search for the multi-spectral image of the sun I was looking for a while back. Just can't find it anymore, which is a shame, 'cause it was awesome, as I recall.

So, I'll settle for the next best thing. A recent image from Hinode that show the same thing I recall seeing in the multi-spectral:

(Hinode's image )

Soft X-ray image in the titanium-polyimide ("Ti_poly") filter from the Hinode X-Ray Telescope (XRT) obtained at: [2008/06/05 18:02 UT]
Obtained from: http://umbra.nascom.nasa.gov/images/latest.html

corresponds rather well to the halo seen in certain configurations of Birkeland's terella experiments, below:

(Birkeland's terella, Fig. 260 a-c; pay particular attention to 260a)

One is also tempted to point to the "pencil jets" from the poles of the sun, reminiscent of Birkeland's description of "pencil" cathode rays issuing from the terella and theorized to also issue from the sun. They seem to give good correspondence to the filaments poking out around the poles of the terella experiment as well...

So, can we learn anything from this? Has Birkeland proven to be prescient, once again?

Likewise, if anyone has or knows of the original multi-spectral / composite image that shows the streamers around the coronal holes, feel free to post a link to it. And, no, it's NOT this one (though it's cool too!)...

I think I recall the image you are talking about... if it is red, green, blue, etc.. very impressive image, one of my favorites... I may even have it in my cd collection over the years.

Let me know if it is and I shall make a search.

Yeah, it was a composite image of the sun. Very colorful and kinda' pretty. I THINK it showed the full disk, with both coronal holes at the poles. But it may have only been a half disk or less (it's been a while). I recall that it quite well showed the filamentary jets ringing the coronal hole(s), and clearly showed the hole(s) themselves. Quite a good match to Birkeland's terella pic, in my opinion, as I recall...

Sadly there's so many satellites these days I'm not sure which it came from, or whether I can even name them all: SOHO, STEREO, RHESSI, TRACE, Yohkoh, Hinode, Ulysses, etc.
I'm pretty sure it was a composite from one or another of those.

Behold?

Hey, that's pretty good. Not sure if it's the exact one I recall (I seem to recall the plumes around the coronal holes being a bit better defined & more prominent somehow). But it's been a while since I saw it. I might just be romanticizing it in my brain, who knows. But for some reason, I feel like I'll remember it when I see it. If it crops up again.

But, a good find nonetheless. Any idea from whence it came? Instrument, gallery, etc? Looks a bit SOHO / STEREO / Hinode-ish?

Always nice to trace things back to original docs.

Don't know if this is it but here is a link

Would post the image inline if I knew how.

Thanks.

hi folks,

regarding that everlasting NUCLEAR FUSION - problem...

As I remember it needs a certain power density for nuclear fission to happen. Are there any relyable data/comparisons on energy density measured in:

- The corona
- The Photosphere

...of our Sun?

I can imagine that it should be relatively difficult for getting any data eg doublelayer in the Chronosphere/Corona as it wouldn´t show any results from the outside and you have to go to the actual location with a Langmuire-probe. So, do you know any method for concluding energy density from the strengths of the magneticfields?

And how large it might be?

Thx in advance for your clues.

Pretty cool & just plain pretty coronal loops...
