     Cometary images have been discovered by C. S. Shoemaker, E. M.
Shoemaker and D. H. Levy on films obtained with the 0.46-m Schmidt
telescope at Palomar.  The appearance was most unusual in that the comet
appeared as a dense, linear bar about 1' long and oriented roughly
east-west; no central condensation was observable, but a fainter, wispy
'tail' extended north of the bar and to the west.  The object was
confirmed two nights later in Spacewatch CCD scans by J. V. Scotti,
who described the nuclear region as a long, narrow train about 47" in
length and about 11" in width, aligned along p.a. 80-260 deg.  At least
five discernible condensations were visible within the train, the
brightest being about 14" from the southwestern end.  Dust trails
extended 4'.20 in p.a. 74 deg and 6'.89 in p.a. 260 deg, roughly aligned
with the ends of the train and measured from the midpoint of the train.
Tails extended more than 1' from the nuclear train, the brightest component
extending from the brightest condensation to 1'.34 in p.a. 286 deg.
The measurements below refer to the midpoint of the bar or train.

   Measurers D. H. Levy, J. Mueller, P. Bendjoya and E. M. Shoemaker.
J. V. Scotti (Kitt Peak).  Last observation made through cirrus.

     The comet is located some 4 deg from Jupiter, and the motion
suggests that it may be near Jupiter's distance.

     D. D. Balam and G. C. L. Aikman report a measurement of V = 20.3
+/- 0.1 and B-V = +0.51 on Feb. 26.28 UT, using the 1.85-m reflector
(+ CCD) at the Dominion Astrophysical Observatory.
