. These two images were obtained by F.Lisi and P.Patriarchi on March 25, 1996, in the J band with an exposure time of 30 sec. The bright spot on the upper left is the comet nucleus, while a fragment is visible near the center of each image. Comparing the two images it is possible to see that the fragment is moving out from the comet nucleus at a speed of 17 m/sec. (Here a postscript version of this image)
