But now the other half of my brain interjects: We are seeing gas flowing between the fields right? So this could be considered wind? Then how fast it is going? The movie description has 450 frames x 3 minutes = 22.5 hrs, but what is the scale of the image? How far apart are the two poles and how tall are they?

And by the way. Where the heck are the hi-res versions? I tried to put this on my laptops wallpaper and it looks like junk. Is this limited by the resolution of the optics floating around up there or by the .gov sites not sharing links to their hi-res folders?

. . . shows the limb of the Sun at a wavelength of 19.3 nanometers . . .

Thank-you so much for using SI units here.

Since the Sun is mostly hydrogen, does that then mean that we’re looking at a big boiling pot of proton soup?

I hope thats a cue. :’(

It’s funny how different the Sun looks at different wavelengths of light. In visible light, you can see all sorts of surface features like sunspots, granules (rising and falling packets of gas convecting like a pot of water on a stovetop), and more.

There’s nothing quite like seeing our Daytime Star rendered vivid crimson by a hydrogen-alpha filter!

A remarkable sight I’d recommend to all.
And when you realise the scale of a sunspot or solar prominence,
Yegods! How it makes our Earth look small! 8)

Great image with the ultra-violent turned amber yellow and black, not true colour but a truer picture than meager human eyes could see.

PS. Earth to scale here woud be how big?
