On behalf of the Carnegie Supernova Project, we report spectroscopic classification of PSN J08293820-1717473 and ASASSN-14my (ATel#6860), based on visual-wavelength spectra obtained with the Nordic Optical Telescope (+Alfosc).

 
 
Name       | RA          | DEC          | Spec. date    | Type | Phase               | Note 
 
PSN J08-17 | 08:29:38.20 | -17:17:47.30   2014 12 27.1  | Ia   | 2-3 weeks post max  |  (1) 
ASAS14my   | 11:38:29.98 | -08:58:35.79 | 2015 01 05.1  | Ia   | near maximum        | 
 

(1) The supernova redshift matches that of the presumed host, MCG-03-22-002, at z=0.018926 (Huchra et al. 2012, Ap.J.S., 199, 26). The spectrum exhibits prevalent host Na I D absorption with an equivalent width of roughly 4 angstroms.
