We conducted two spectroscopic observations of transient ASASSN-15jm at
2015-05-21T:00:45:16 and 2015-05-22T00:33:10 UT.
This transient was identified by the All Sky Automated Survey for
SuperNovae (ASAS-SN) in ATel #7536 in host galaxy 2MASX J17210913+2534558.
Two spectra were obtained in the visible, 400-800nm, with resolution
R~350, using the SPRAT spectrograph on the Liverpool Telescope located
at Roque de los Muchachos.
Classification using SNID (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) indicates it is a type Ia supernova with closest matching spectrum
SN2003hu and estimated z=0.05.
