PSN J10520833+3256394 was independently discovered by the intermediate Palomar Transient Factory on UT Dec 6 when we switched to monitor new fields. It was internally designated as iPTF15eqv.

We obtained a spectrum of iPTF15eqv on UT 2015 Dec 07.53 with the Double Spectrograph mounted on the 200-inch Hale Telescope at Palomar Observatory. The spectrum shows weak continuum emission superposed by strong Ca II and weak Halpha emission lines. Therefore, iPTF15eqv is probably a Type IIb supernova (or maybe Type Ib) in the nebular phase.
