The program started in 2011 with the aim to classify all transients that are accessible from Asiago and are bright enough for our telescope/instrumentation. We use mainly the 1.82m Copernico telescope of Cima Ekar and, if not available, the 1.22m Galileo telescope of the Pennar station. A few cases of transients classified by our group with other facilities (eg. TNG) are included in the database.
Transient classification information and spectra (fits format) are made immediately available at our site. The spectra are semi-automatic reduction with archive calibration data. Please keep this in mind when using them.
For SN classification we compare the output of two automatic SN classification codes: Gelato (Harutyunyan et al. 2008, A&A 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).

Discovered by: ISSP
The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of AT 2016fmt discovered by Fabrizio Ciabattari of the Italian Supernova Search Project (ISSP) in NGC 606, who reports a discovery magnitude of 17.8 on UT 2016-08-28 02:52:48.
The observations were performed with the Asiago 1.82 m Copernico Telescope equipped with AFOSC (range 340-820 nm; resolution 1.4 nm).

(1) The low S/N spectrum shows a blue continuum with shallow Balmer lines. This is a young Type II SN, in agreement with the Transient Name Server (TNS) report of Liming Rui(THU), Xiaofeng Wang(THU), Tianmeng Zhang(NAOC), Junjun Jia(NAOC). A match is found with the type II-P SN 1999gi a few days after the explosion. The redshift z=0.03322 as obtained from the Halpha emission of the host galaxy.
