THE PROBABLE COLLISION OF P SHOEMAKER-LEVY-9 (1993E) WITH JUPITER IN 1994/

The results of numerical integrations, based on the orbit of P/Shoemak er-Levy 9 available in June 1993, have definitely shown that many, if not all, of the fragments of the comet will collide with Jupiter in Ju ly 1994. This paper, written at the-time of the Belgirate ACM '93 Meet ing, should be regarded as of historical importance: many more observa tions have been made since then, and are being-made at present, making the numerical computations reported here quite obsolete. The comet fr agments are now under continuous surveillance;
