Shoemaker, E. M. Shoemaker, and D. H. Levy report their discovery on Palomar 0.46-m Schmidt films of yet another comet, as given below. The object is diffuse with a faint tail in p.a. about 280 deg. 1991 UT R.A. (1950) Decl. m1 Feb. 9.455 12 09.5 + 2 31 17 11.272 12 08.8 + 2 43 SUPERNOVA 1991E IN ANONYMOUS GALAXY R. H. McNaught, University of Adelaide, reports his discovery on a U.K. Schmidt Telescope plate taken Feb. 7.47 UT by M. Hartley of an apparent supernova of magnitude R about 19 in an anonymous galaxy. The position of the supernova is R.A. = 6h34m14s.89, Decl. -65 30'39".1 (equinox 1950.0), or 6".3 east and 5".0 north of the galaxy's center. No image appears in this position on the ESO B, R, SERC I, J, and several other J plates. A nearby star of mag about 16 is at R.A. = 6h34m10s.63, Decl. = -65 30'09".8. SUPERNOVA 1991D IN ANONYMOUS GALAXY R. Kirshner, Center for Astrophysics, communicates: "Spectra of SN 1991D obtained on Feb. 10 and 11 by J. Huchra and J. McAfee at the Multiple Mirror Telescope indicate that this appears to be a type-Ib or -Ic supernova. Although the maxima at 390, 415, 440, and 490 nm are like those seen in type-Ia supernovae, no absorption at 615 nm is detected. The supernova is offset 13".1 east and 8".5 south of the galaxy nucleus at R.A. = 13h38m32s.5, Decl. = -14 23'39" (equinox 1950.0). The galaxy redshift is about 12 300 km/s. When combined with the apparent magnitude reported on IAUC 5182, this implies that SN 1991D is as luminous as a type-Ia supernova." COMET LEVY (1990c) Total visual magnitude estimates (cf. IAUC 5172): Jan. 24.50 UT, 7.6 (A. Hale, Las Cruces, NM, 10x50 binoculars); Feb. 6.35, 7.6 (Hale); 9.62, 7.9 (M. Ohkuma, Mt. Fuji, Japan, 10x70 binoculars). 1991 February 11 (5185) Daniel W. E. Green
