Maza, Astronomy Department, University of Chile; and M. Phillips and N. Suntzeff, Cerro Tololo Interamerican Observatory,telex: "M. Wischnjewsky has discovered a supernova at R.A. = 3h35m24s.2, Decl. = -33 12'21" (equinox 1950.0), which is 1".2 E, 5".2 S of the nucleus of an anonymous elliptical galaxy. The supernova (estimated B = 18) was found on a 15-min 103a-O plate taken through a GG385 filter by L. Wells and Wischnjewsky with the Curtis Schmidt telescope on Aug. 22.36 UT. Confirmation was made by S. Howell and P. Szkody, who obtained BVR CCD images with the CTIO 0.9-m telescope on Aug. 29.40; their preliminary magnitudes and colours from these data are V = 17.7, B-V = +0.8, and V-R = +0.2." IAUC 5080 SUPERNOVA 1990Z IN UGC 12133 J. Mueller reports her discovery of a supernova in UGC 12133 (R.A. = 22h37m.0, Decl. = +8 22', equinox 1950.0), located 25".5 W 30".2 S of the galaxy's centre. The estimated magnitude of the supernova is 19 on a red plate taken Aug. 21 UT with the 1.2-m Oschin Schmidt Telescope in the course of the second Palomar Sky Survey. A spectrum indicates that the object is a type-II SN. IAUC 5082 V348 SAGITTARII This unusual R CrB-type variable is again fading, as indicated by the following visual magnitude estimates (cf. IAUC 4821): Apr. 29.09, 11.8 (M. Verdenet, Bourbon-Lancy, France); July 6.17, 12.0 (J. E. Bortle, Stormville, NY); Aug. 16.86, 11.8 (Verdenet); 17.86, 12.2 (Verdenet); 18.8, 12.8 (T. Cooper, Benoni, R.S.A.); 18.85, 12.6 (Verdenet); 19.7, 12.8 (D. Overbeek, Edenvale, R.S.A.); 19.87, 13.0 (Verdenet); 20.86, 14.2 (Verdenet); 23.46, 14.6(Royer) IAUC 5082 V632 CYGNI (cf E439) Stefan Korth reports a further result: Aug 24.985UT, 15.4. G.Dyck, USA, advises he confirmed the outburst on Aug 29.08UT at 14.2. BAA COMET SECTION MEETING This will be held on 1990 October 6 at the Institute of Astronomy, Cambridge, England.
