Supernova 1995P in Anonymous Galaxy
Abstract
R. H. McNaught, Anglo-Australian Observatory, reports his discovery of a supernova (mag about 18) found on a J plate taken by M. J. Drinkwater with the U.K. Schmidt Telescope (UKST) on May 6.5 UT and located at R.A. = 14h07m14s.33, Decl. = -2o43'32".7 (equinox 2000.0; uncertainty 0".3 in each coordinate), which is 1".3 east and 4".6 north of the galaxy's center. No star appears to mag about 19 on a 3-min R film taken by Q. A. Parker with the UKST on Feb. 27.7. A nearby star of mag 17 has position end figures 14s.17, 07".5. B. Schmidt, Mount Stromlo and Siding Spring Observatories (MSSSO), communicates that a spectrogram was taken with the MSSSO 2.3-m telescope, revealing broad features that are most consistent with a type-Ia supernova about 6 weeks past maximum; other types can not be unequivocally ruled out due to the very poor signal of the spectrum. S. Benetti and M. Turatto, European Southern Observatory, write: "We have observed SN 1995P on May 30.2 UT with the New Technology Telescope (+ EMMI) at La Silla under non-photometric conditions. A spectrum (range 380-846 nm, resolution 1 nm) closely resembles those of the type-Ia SN 1994D, about 1 month past maximum light (cf. Patat et al. MNRAS, in press). In particular, the slopes of the continua are similar, indicating that both supernovae suffered the same amount of reddening. Broad emissions are measured at 488, 511, 523, 585, 616, and 688 nm. SN 1995P is located 1".1 east and 4".7 north of the nucleus of a lenticular parent galaxy. Its redshift, determined from Ca II (H and K), Mg I, and Na I absorption lines, is 0.056."
