This text replaces Atel #6640. We revised Gaia14acg classification and corrected an error in the classification dates: The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of three supernovae. The observations were performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.2 nm). Name | Date (UT) | z | Type | Phase | Notes MASTER OT J120451.50+265946.6| 20141029.14 | 0.00189 | Ib | ~3 weeks | (1) MASTER OT J113930.78+251141.0| 20141029.12 | 0.01226 | II | ~1 month | (2) Gaia14acg | 20141029.17 | 0.03145 | Ia | ~2 weeks | (3) (1) Host galaxy NGC 4080; from the distance modulus m-M=28.74 (Virgo + GA + Shapley) and the magnitude at discovery, we deduce an absolute magnitude around -14.8 mag. Discovered by MASTER robotic Net (ATel #6634, #6639). (2) Host galaxy PGC 2817170; discovered by MASTER robotic Net, ATel #6595. (3) The transient Gaia14acg was detected by the Gaia Photometric Science Alerts programme with a magnitude of 17.8, 2014 Oct. 23. BP and RP spectra indicated a likely SN. The host galaxy is UGC 8352, at z = 0.031145 (Huchra et al. 1995, ApJS 99, 391 via NED). Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024).
