Wiggins, Tooele, UT, USA, reports his discovery of a possible supernova (mag about 12.8) on an unfiltered CCD frame taken 2017 May 14.2383 UT using a 0.35-m f/5.5 reflector near Erda, UT, USA. The new object is located at R.A. 20h34m44.24s, Decl. +60°11’35.9” (equinox 2000.0), about 153” NW of the center of NGC 6946.

MadoreASAS-SNSN Ia1ASAS-SNWe report an optical spectrum (range 370-920 nm) of ASASSN-16jc/AT2016fej obtained on UT 2016 Aug. 30.0 with the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory. We performed a cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024). The spectrum of ASASSN-16jc is most similar to the spectrum of the normal SN2007F at -6 days before maximum light.

34502019-01-28 20:58:37lgalbanyLluís Galbany, J. P. AndersonNoneSN Ia0.020721While looking at archival VIMOS data of SN host galaxies in the ESO archive, we found that one of the observations of NGC 0692 had a bright source that was not present in archival DSS images. We extracted a 2-arcsec aperture spectrum (4850-10000 A) at that location, and it clearly showed the main features of a type Ia supernovae at maximum light (S II W, Si II 5972 A, and Si II 6355 A). Host galaxy emission lines were superposed to the SN spectrum, and we measured a redshift of 0.02072 from H-alpha (in agreement with the galaxy redshift reported in NED, 0.02118). We estimate a Si II 6355 velocity of 12100 km/s. Comparing the SN spectrum with templates of several SNe of different types, GELATO (Harutyunyan et al., 2008, A&A, 488, 383) found the best fit to SNIa 2005am at +2.7 days past B-band maximum.
