This is a copy of a Press Release from E.S.O. The most recent ESO observations of bright Comet Hyakutake have shown rapid changes in the innermost coma, within a few hundred kilometres from the cometary nucleus. This result has only become possible because of the unusual combination of a bright comet being near the Earth, together with the excellent imaging quality of the ESO 3.5-metre New Technology Telescope (NTT). ...

. 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)

... The comet 169P was first observed by the Near-Earth Asteroid Tracking system. In order to observe this comet we had to figure out if it was possible to view it from Faulkes Telescope South, a 2m reflecting telescope which is used for research as well as for use by school students around the world over the internet. ... Since 169P is such a bright object, we were able to use a red filter on some of our observations to provide a clearer image. ...
