COMET SHOEMAKER (1992y)
Carolyn S. Shoemaker reports her discovery of a comet on films
taken by E. M. Shoemaker, D. H. Levy, and H. Holt with the 0.46-m
Schmidt telescope at Palomar. There is a tail fanned toward the
south-southwest. D. D. Balam, University of Victoria, provides a
precise position obtained with the 0.25-m Schmidt telescope.

SUPERNOVAE 1992bg AND 1992bh IN ANONYMOUS GALAXIES
J. Maza, University of Chile; and M. Hamuy, Cerro Tololo
Interamerican Observatory, report the discovery by R. Antezana,
University of Chile, of two supernovae on 20-min unfiltered IIa-O
plates taken by G. Valladares with the CTIO Curtis Schmidt
telescope. SN 1992bg (mpg about 17.8 on the Oct. 21.34 UT
discovery plate) is located about 3" west and 6" north of the
nucleus of a spiral galaxy at R.A. = 7h41m19s.0, Decl. = -62 24'06"
(1950).
SN 1992bh (mpg about 17.3 on the Oct. 21.32 discovery plate) is
located about 1" east and 2".5 south of the nucleus of a spiral
galaxy at R.A. = 4h58m40s.0, Decl. = -58 54'10". Confirmation of
both supernovae was made by M. Navarrete (CTIO) on CCD B,V, and I
images obtained on Oct. 24.31 with the CTIO 4-m telescope.
