SOLAR WATCH * Huge X8.2 Flare Sept. 10, 2017! (Updated Daily)

Jan 23, 2013 - Why NASA Scientists Observe the Sun in Different Wavelengths
Taking a photo of the sun with a standard camera will provide a familiar image: a yellowish, featureless disk, perhaps colored a bit more red when near the horizon since the light must travel through more of Earth's atmosphere and consequently loses blue wavelengths before getting to the camera's lens.
The sun, in fact, emits light in all colors, but since yellow is the brightest wavelength from the sun, that is the color we see with our naked eye -- which the camera represents, since one should never look directly at the sun. When all the visible colors are summed together, scientists call this "white light."
snip:
Each wavelength was chosen to highlight a particular part of the sun's atmosphere.
From the sun's surface on out, the wavelengths SDO observes, measured in Angstroms, are:
+ 4500: Showing the sun's surface or photosphere.
+ 1700: Shows surface of the sun, as well as a layer of the sun's atmosphere called the chromosphere, which lies just above the photosphere and is where the temperature begins rising.
+ 1600: Shows a mixture between the upper photosphere and what's called the transition region, a region between the chromosphere and the upper most layer of the sun's atmosphere called the corona. The transition region is where the temperature rapidly rises.
+ 304: This light is emitted from the chromosphere and transition region.
+ 171: This wavelength shows the sun's atmosphere, or corona, when it's quiet. It also shows giant magnetic arcs known as coronal loops.
+ 193: Shows a slightly hotter region of the corona, and also the much hotter material of a solar flare.
+ 211: This wavelength shows hotter, magnetically active regions in the sun's corona.
+ 335: This wavelength also shows hotter, magnetically active regions in the corona.
+ 94: This highlights regions of the corona during a solar flare.
+ 131: The hottest material in a flare.

Fo'sho'!

Here are the Two South-Eastern Filament Ejections in 171 [link to sdodata.oma.be] Jah.

Thanking you ta' and Hello JCA

Hope all is relative for you Bro'.

Thankfully, it doesn't look like Peewee Herman!

Hello SC..... Thank you and everyone else for all that is contributed to this great sun thread!

Everybody should bookmark this Russian's YT channel. This person is a super-suntard-deluxe! I wish I could read the Russian descriptions.

Here's the earlier southern filament liftoff which produced the CME today-

HAHAHAHAHA...

Good night all. :-)

:SmilieZzBear:

HAHAHAHAHA...never forget the Teddybear....

f***


but this is the triangle expansion corner forming ... out of the Sphere

amazinnn

I was going with a head of steer, but this works, lol

Oh, so glad you are A.O.K.!!

First link wouldn't load, second was awesome bit of info. Thanks,

I saw that coming!

Excellent comparison, I take my head of steer comment back. I also get a little Phantom of the Opera....or this....

Very helpful, thanks! I do look right at the sun right before sunset (google sungazing). Its incredible the effect it has on my heart chakra, it powers it up so beautifully.

Hi SC! Is that first filament eruption the same one we were looking at yesterday? Is so, I don't remember it getting sucked back toward the sun like this one. Also, see a little coronal cavity trying to set up between 6 and 7 on the dial. Last, did you notice the bright flash right on the south pole at the very end of the vid? What was that?

that's some mad skills there, cool.

exquisite performance by our principal dancer Sol!!

I would love to get a full view of that whopper CH lurking beneath the canopy of the corona.

OK, all caught up, everyone, another fantastic day of sun 'ploring, LOVE IT, and you guys, I am out now for an official nights sleep. C ya on the flip side!

yes it looks some kind of giant diferent light resides there on the inside...

almoust like a new star system design Eye on the real top of the Piramid !!!!


and this coincidences of the piramide in the SUn. the piramides on Earth all over., the piramide on dollar notes

hummmmmm this is to much coincidence


and should be related properly
what the hell is going on here???

That sunspot is way up there.

Coronal hole is looking bigger now, too.
