The spectrum reveals strong signatures of circumstellar material (CSM) interaction, consistent with a Type IIn supernova at redshift z = 0.019. The H-alpha emission line exhibits a narrow P Cygni component (absorption minimum ~850 km/s) superimposed on an intermediate-width component (~6,400 km/s). In addition, we detect emission features from He I, O I, Fe II, Ca II, and [Ca II].
