1992IAUC.5456....1W Circular No. 5456 Central Bureau for Astronomical Telegrams SUPERNOVA 1992H IN NGC 5377 William Wren, McDonald Observatory, reports his visual discov- ery of a supernova located about 57" east and 19" north of the nuc- leus of NGC 5377 (R.A. = 13h54m.3, Decl. = +47 29', equinox 1950.0). Nothing appears at this position on the Palomar Sky Survey. SN 1992H was near mv about 15.0 at discovery on Feb. 11.50 UT, and the brightness has remained near this level on Tech Pan photographs tak- en by Wren on Feb. 13.37, 13.40, 15.31, 16.33, 17.36, 17.39, 21.24, and 21.27. T. Iijima, M. Turatto, and E. Cappellaro, Asiago Observatory, report that a spectrogram (resolution about 1 nm) of SN 1992H was obtained with the 1.82-m telescope (+ Boller & Chivens spectrograph + CCD) on Feb. 21.07 UT. A preliminary inspection of the spectrum shows a blue continuum with broad H-alpha (FWHM about 25 nm) and no sign of P-Cyg absorption, resembling the type-II linear supernovae 1979C and 1980K when 2-3 weeks past maximum light. 1992 February 21 Daniel W.
