Solar Views from SOHO (Wallpapers)

Back in 2006, I was feeling a bit nostalgic about my four years of research at the University of Wales, Aberystwyth Solar Group, so I decided to try to find some high resolution prints of the Sun. After a lot of effort, I didn’t find any prints I could buy or download, but I did find some high resolution images from the Solar and Heliospheric Observatory (SOHO) image archive. Although some were a bit noisy, I was able to clean them up with Photoshop and did some layer tweaking/saturation/balance to draw out the fine detail of the chromospheric network–as seen above in the 304A Extreme ultraviolet Imaging Telescope filter–plus a distinct prominence (in the bottom left-hand of the image).

Not stopping there, I decided to give the same treatment to high resolution 171A and 195A images. They came out very well and I kept rotating them as my wallpaper for months. Having just read Phil’s post on today’s perihelion (the time of year when the Earth is at its closest to the Sun during its orbit), I came across a comment asking whether anyone had any wallpapers of the same 304A EIT image. Well, here it is! Plus two more!

If anyone wants to find out how the images were edited, feel free to ask and I’ll let you know. Truth be known, there’s thousands of space images held by NASA, ESA etc. open to the public domain that rarely get the “airtime” they deserve. So it’s about time I dust off these three-year old edits and share the magnetohydrodynamic love.

I miss active regions, I wish the Sun would amp it up a bit so we can see all those lovely flares, CMEs, filaments and coronal loops… ahhhh… coronal loops
