- COMET 1991b1
- Carolyn and Eugene Shoemaker and David H. Levy report their
- discovery, on 0.46-m Schmidt films taken at Palomar, of a fast-
- moving comet. Approximate positions follow:
-
- 1991 UT R.A. (1950) Decl. m1
- Nov. 7.190 0 07.0 - 1 35 13
- 9.193 0 11.5 + 1 50
- 10.156 0 14.3 + 3 33
-
- The comet is strongly condensed on the films, with a coma of diamet-
- er about 30". On Nov. 10.16, there was a tail about 1' long toward
- the east; at about this same time, Levy estimated m1 = 12.7 visually
- in a 0.15-m reflector.

- SUPERNOVA 1991be IN ANONYMOUS GALAXY
- R. H. McNaught, Anglo-Australian Observatory, reports his dis-
- covery of a supernova (mag about 18.5) on a J plate taken by M. J.
- Drinkwater with the U.K. Schmidt Telescope on Nov. 7.4 UT. The sup-
- ernova is situated towards the edge of the galaxy, offset from the
- center by 7" west and 1" south. Coordinates for the supernova are
- R.A. = 21h30m03s.90, Decl. = -42 26'05".3 (equinox 1950.0, uncer-
- tainty 0".5 in each coordinate). Images appear on U.K. Schmidt J
- plates taken by S. M. Hughes on Oct. 31.4 and Nov. 1.4 when it was
- somewhat fainter at mag about 19. A nearby star of mag about 17.5
- is at R.A. = 21h30m08s.27, Decl. = -42 25'48".8.
