Scientific paper

An intensity calibrated spectrum in the range 4200 Å to 7100 Å of a Type I supernova about 7 weeks after maximum is presented. Strong broad emission lines are observed but no P Cygni profiles or conspicuous absorption lines. The emission lines can be attributed to transitions of ions of helium and oxygen. Traces of hydrogen are possibly present but no carbon and nitrogen lines are detectable.
