SOHO’s SWAN (Solar Wind ANisotropies) observes backscattered photons, that is the satellite can detect specific wavelengths of light reflected back to it from neutral hydrogen atoms surrounding the sun. This allows computers to reconstruct a rough image of the activity on the side of the sun not facing the earth. This is one of the ways that scientist are now able to predict upcoming solar activity.

| I constructed the above Flash animation from this gif animation. It’s composed of six images from Oct 24, 26, 31, Nov 5, 7 and 11. The original gif so confused me, that I put the farside image into this format, dissolving between the images to make the timescale more consistent. Flash’s jpeg compression also helps bring the file size way down to 10% of the original gif). The black areas in the middle of the images indicates not enough information from the backscatter to say what is going on there. |
