We report the spectroscopic classification of supernova ASASSN-15od discovered by the All Sky Automated Survey for SuperNovae ~1.1" from the center of the galaxy MCG -01-07-004 (ATel #7907). The classification is based on a low-resolution spectrum obtained on Aug. 15.14 UT with the Nordic Optical Telescope (+ ALFOSC; range 320-910 nm).

The spectrum is consistent with a normal Type Ia supernova about a week before the maximum light.

 
Name             | RA (J2000)   | Dec (J2000)  | Disc. Date   | Disc. Mag. |  z     | Type    | Phase              | Notes 
ASASSN-15od | 02:23:13.21 | -04:31:02.05 | 2015-08-10.51| 17.4 | ~0.018 | SN Ia | ~1 week before max | (1)

(1) Matches found with several normal Type Ia SNe about 1 week before the max. light.

The classifications were done with GELATO (Harutyunyan et al. 2008, A&A,488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024).
