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).

The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of SN 2017A. The target was supplied by Duszanowicz and Tsinghua-NAOC (RANSSP).
The observations were performed with the Asiago 1.82 m Copernico Telescope equipped with AFOSC (range 340-820 nm; resolution 1.4 nm).
IAU Name | Host galaxy | Redshift | Discovery Date | Discovery mag | Classification (UT) | Type | Phase | Notes SN 2017A | UGC 10104 | 0.0328 | 2017-01-01.23 | 17.4 | 2017-01-24.19 | Ia | +30d | (1)
(1) The AFOSC spectrum is similar to that of normal Type Ia, around one month after maximum light. The redshift of the host galaxy comes from Haynes et al. 1997, AJ, 113, 119, via NED.
