Spaceweather.com has a great animated image on the site today showing the spreading of the Jupiter impact cloud. This was discovered several weeks ago by Anthony Wesley in Australia and has become known as the "Wesley impact site". Lucky guy!
German astronomer Hans Joerg Mettig has converted some of the best images into polar projections showing the movement and dispersion of the cloud. I'm not sure if these are the "best" of all the photos out or Wesley's excellent shots. Whatever they are, they make an impressive little animation.
