Supernovae 1992ae and 1992af
Abstract
L. Wells, Cerro Tololo Interamerican Observatory; and J. Maza, University of Chile, report the discoveries by R. Antezana (University of Chile) of two apparent supernovae on unfiltered 20-min IIaO exposures taken by L. Wells with the CTIO Curtis Schmidt telescope. SN 1992ae, at mpg about 18 on June 27.30 UT, is located 3" east and 5" north of the nucleus of an anonymous galaxy (R.A. = 21h24m26s.8, Decl. = -61 46'12", equinox 1950.0). SN 1992af, at mpg about 17.5 on June 29.28, is located 10" east and 3" south of the nucleus of the spiral galaxy ESO 340-G38 (R.A. = 20h27m17s.0, Decl. = -42 28'39"). Confirmation of both SNe 1992ae and 1992af was made by K. Wakamatsu (Gifu University) and M. Malkan (University of California, Los Angeles) from B and V CCD images obtained on July 2.31-2.32 with the CTIO 0.9-m telescope, and by C. Anguita (University of Chile) from B and V images obtained on July 2.32- 2.33 at the CTIO 1.5-m telescope.
