Williams and R. Martin, Perth Observatory, report their discovery, during the Perth Astronomy Research Group's automated supernova search on the Perth-Lowell 0.61-m reflector, of a supernova (R about 16) on Mar. 12.538 UT. SN 1996N is located 46" east and 12" north of the centre of NGC 1398 (R.A. = 3h38m.9, Decl. = -26o20', equinox 2000.0). Nothing was visible at this location on Feb. 16. IAUC 6351 SUPERNOVA 1996O IN MCG 03-41-115 B. Schmidt, Mount Stromlo and Siding Spring Observatories, e-mails: "R. O. Evans reports his discovery of a supernova of mag about 18 on a U.K. Schmidt R film taken by P. Cass on Mar. 21 as part of the U.K. Schmidt Supernova Search. SN 1996O is located at R.A. = 16h06m00s, Decl. = +18d11'.8 (equinox 2000.0), 20" west and 2" south of the nucleus of MCG 03-41-115. The object was not visible on a similar film taken in Aug. 1995. IAUC 6352 SUPERNOVA 1996P IN NGC 5335 J. Mueller reports her discovery of a supernova (mag about 17) found on a IIIa-J plate taken on Mar. 25 UT by K. M. Rykoski and herself with the 1.2-m Oschin Schmidt telescope in the course of the second Palomar Sky Survey. SN 1996P is located 57".8 west and 22" south of the centre of NGC 5335 (R.A. = 13h53m.0, Decl. = +2o50', equinox 2000.0). No object appears at this position on original Sky Survey prints or on a second Sky Survey transparency taken by Mueller and D. J. Mendenhall on 1990 May 18. IAUC 6357 UV PERSEI Eric Broens, Belgium, reported UV Per (UG-type) bright on 1996 Mar 14.836UT at mv=11.9. This was confirmed on Mar 14.882T by Tonny Vanmunster at mv=12.1. (CVC 86) The star is on the Recurrent Objects Programme of the UK Nova/Supernova Patrol. Reports from the AAVSO indicated that by Mar 18 the star could not be detected to a limit of 14.1. A further brightening then took place and on Mar 26.79UT L.Jensen in Denmark estimated it at mv=12.5. By Apr 1, Zissell using CCD with V filter measured it at V=16.6. The same observer then reported it brightening by Apr 3.04UT to V=-13.9. The unusual behaviour of this star, suspected on several occasions in TA records in the past when it was less well observed, justifies increased monitoring despite the current low altitude of the field. GO COM Taichi Kato advised us via VSNET that Makoto Iida had detected an outburst of GO Com but no specific data was available. On Mar 26.634UT the Ouda team in Japan confirmed it was bright at V=14.84 using the 0.60-m reflector. This star is also on the Recurrent Objects Programme. Guy M Hurst
