Foley (UCSC)UCSCSN IIn0.035UCSCThe spectrum is blue and has narrow He I and He II features. He II 4686 has a narrow P-Cygni profile with the absorption blueshifted by -460 km/s, while He I 6678 has a broader absorption feature with a minimum blueshifted by -1300 km/s. There are unresolved H Balmer lines, but it is unclear if they originate from the host galaxy. ATel: 142642020TNSCR3770....1S
