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.

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.

Wiggins, Tooele, UT, USA, reports his discovery of a possible supernova (mag ~17.0) on an unfiltered CCD frame taken 2020 Feb 26 10:01:22 UT using a 0.35-m f/5.5 reflector near Erda, UT, USA. The new object is located at R.A. 20h37m10.72s, Decl. +66°06'12.80" (equinox 2000.0), about 22” SW of the center of NGC 6952. Wiggins notes that nothing was visible at this position on an image taken the day before, however the seeing then was very poor.

Comparing with spectra using SNID ( Blondin, S. & Tonry, J. L. 2007. ApJ, 666, 1024) gives a good match to several type IIP supernovae around 25 days after maximum
