Something new under the Sun? Indeed!

Images from two of SOHO's instruments have been given a whole new look. The original files have been processed using an algorithm that allows the visualization of much sharper features than those in the raw images. The results are striking, revealing structures that have never been seen before in the originals. In a major processing effort, the new "wavelet" processing has been applied to virtually all of the EIT 195 and LASCO C2 images and made into MPEG movies. The samples above show the original movies and the wavelet movies side by side.

More detailed explanation of this process can be found here: SOHO began its Weekly Pick some time after sending a weekly image or video clip to the American Museum of Natural History (Rose Center) in New York City. There, the SOHO Weekly Pick is displayed with some annotations on a large plasma display.

If your institution would also like to receive the same Weekly Pick from us for display (usually in Photoshop or QuickTime format), please send your inquiry to
