Visual observations by M.Yamada of Ishikawa, Japan follow: 1993 Jan 1.781UT, 11.1; 2.781, 11.0. AAVSO Circulars give the following values: 1992 May, 11.8 (4 observers); June, 11.5 (4 observers); July, 11.2 (G.Lubcke); Aug, 11.2 (Lubcke); Sept, 11.2 (Lubcke). GVCS (III) has 11.2mpg. A report by Von D.Bohme, Nessa, Germany appeared in Die Steine. 57 Band, Heft 1, p53-56 which quotes the amplitude as 0.85B, B-V = -0.4mag, maximum magnitude 11.2p, dimensions 1.3 x 2.3', distance 19 Mpc. A visual light curve suggests that from a study ranging JD 2442000-2444000 the peak magnitude was 11.0 but that the majority of measures were about 11.8 (AAVSO records).

Maza, University of Chile; and M. Hamuy, Cerro Tololo Interamerican Observatory, report the discovery of two supernovae on 20-min unfiltered IIa-O plates taken by G. Valladares with the CTIO Curtis Schmidt telescope. SN 1992br, of mpg about 18.5, was discovered by M. Wischnjewsky on an exposure on 1992 Dec. 27.09 UT and is 2".5 east and 7" south of the nucleus of an anonymous galaxy at R.A. = 1 43 55.4, Decl. = -56 20 57 (equinox 1950.0). SN 1992bs, of mpg about 18, was discovered by L. Gonzalez on an exposure on Dec. 28.17 UT and is 9" west and 4" north of the nucleus of an anonymous spiral galaxy at R.A. = 3 27 37.2, Decl. = -37 26 38 (equinox 1950.0). IAUC 5686 Guy M Hurst
