A collection of nice images produced from SOHO/MDI observations

The still images below are shown as small gif files and are available by clicking on the image, as larger images either jpeg or gif. They are also available in higher resolution postscript. In the case of movie files, representative frames are shown as small and larger gifs with both mpeg and quicktime video. Some of the movie files are in non-standard form factors and may not play on all PC and Mac platforms. They all work fine on SGI and Linux platforms and will be remade and cross checked as time permits. the order of these images is at present, random.
