The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of PSN J13443367+0446535 in UGC 8690. Information on this transient, discovered by F. Ciabattari, E. Mazzoni and S. Donati (Italian Supernovae Search Project) was announced through CBAT Transient Object Followup Reports (http://www.cbat.eps.harvard.edu/index.html) and is also available from the "Bright Supernova" website (http://www.rochesterastronomy.org/snimages/). The observation was performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.3 nm).
Name | Date (UT) | v | Type | Phase | Notes PSN J13443367+0446535 | 20150411.90 | 6938 km/s | II | 1 month | (1)
(1) The expansion velocity of the ejected material, as inferred from the position of the absorption of the Halpha, is about 7800 km/s.
Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
