An optical spectrogram (range 350-870 nm), obtained on 2014 Jun. 04.85 UT with the 2.4-m telescope (+YFOSC) at LiJiang Gaomeigu Station of Yunnan Observatories, shows that PSN J19223915+4353269 is a type Ia supernova at about two weeks after the maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that it matches with SN 2007le at t = +15 days. Adopting a redshift of 0.045 for the anonymous host galaxy from the SNID fit, they measure a velocity of the Si II 635.5-nm absorption feature to be about 10000 km/s.
