Padova-Asiago Supernova Group
The Asiago Transient Classification Program

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).
If you use some of the information posted in these pages please make a reference to the paper Tomasella etal. 2014, A.N. 335, 841.

SN 2017fof in UGC 10602
SN 2017fof in UGC 10602
Discovered by: Italian Supernovae Search Project ISSP

The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of AT 2017fof, discovered by S. Leonini, M. Conti, L.M. Tinjaca Ramirez and P. Rosi (Italian Supernovae Search Project ISSP) in UGC 10602.

The observation was performed with the Asiago 1.82 m Copernico Telescope equipped with AFOSC (range 340-820 nm; resolution 1.4 nm).

Survey Name   | IAI Name      | Discovery date (UT) | Discovery mag | Observation (UT)    |  Type  | z        | Notes|
AT 2017fof    | SN 2017fof    |2017-07-16 21:21:23  |      17.56    |2017-07-20.88        |  SN Ia | 0.028308 | (1)  |

(1) The spectrum is consistent with that of a Type Ia SN 1991bg-like events few days before maximum light, at a redshift 0.028308, according to the redshift of the host galaxy UGC10602 (Sloan Digital Sky Survey Data Release 1). The expansion velocity deduced from the SiII 635.5 nm absorption is about 11600 km/s. The Sloan-r magnitude measured on our frames is 17.83+-0.05.

Classification were 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
