Perlmutter et al) report eleven supernovae found with the Cerro Tololo (CTIO) 4-m telescope in their 1995 High Redshift Supernova Search: SN 1995 UT R.A. (2000) Decl.

Tokarz and P. Garnavich, Center for Astrophysics, report their discovery of a supernova from the spectrum of an anonymous galaxy observed for the 15R Redshift Survey directed by M. Geller: "The galaxy (magnitude R about 15.0 via M. Kurtz) is an edge-on spiral or irregular located at R.A. = 0h16m17s.64, Decl. = +12o24'53".4 (equinox 2000.0). The overall spectrum is similar to that of the type-Ib supernova 1985F, about 300 days after maximum (Schlegel and Kirshner 1989, A.J. 98, 577).The supernova may have reached mpg about 13 early in 1995, and prediscovery observations are needed to determine the time of maximum." IAUC 6271 NOVA CASSIOPEIAE 1995 Despite the sustained cloudy weather preventing many observations of this nova from Europe, reports from Japan and other countries indicate the nova is increasing in brightness rapidly although there may now be a further pre-maximum halt at around mag 7.1. An updated light curve showing this recent activity has already been placed on the World Wide Web pages of 'The Astronomer' and the URL of our home page appears in the heading of this circular. Observers are urged to monitor this object at every opportunity as the light curve is certainly unusual and may resemble HR Del. Please ensure the revised sequence (which will be extended if necessary) shown on E1021 is used. Guy M Hurst
