Supernovae 1993A and 1993B in Anonymous Galaxies
Abstract
J. Maza, University of Chile (UC); and M. Hamuy, Cerro Tololo Interamerican Observatory, report the discovery of two supernovae on 20-min IIa-O exposures taken by G. Valladares with the CTIO Curtis Schmidt telescope. SN 1993A, at mpg about 18.5 on Jan. 17.17 UT, was discovered by M. Wischnjewsky (UC) and is located 5".5 west and 3".5 south of the nucleus of a galaxy at R.A. = 7h38m38s.4, Decl. = -61 56'11" (equinox 1950.0); the supernova was not visible (mpg > 20) on a IIIa-J plate taken on 1992 Dec. 29. Confirmation of SN 1993A was made by C. Anguita (UC) with a CCD V image obtained on Jan. 20.24 with the CTIO 1.5-m telescope. SN 1993B, at mpg about 18 on Jan. 17.22, was discovered by R. Antezana (UC) and is located about 1" east and 5" north of the nucleus of a spiral galaxy at R.A. = 10h32m35s.1, Decl. = -34 11'03"; SN 1993B was not visible (mpg > 19) on a IIa-O plate taken on 1992 Dec. 27. Anguita also confirmed SN 1993B on CCD B and V frames obtained on Jan. 20.30.
