Scientific paper

The spectrum of the supernova SN1987L in NGC 2336 over the wavelength range 4000-9700 A as recorded in one 500 s exposure on October 20, 21, 1987 is presented. This spectrum was taken using the new Faint Object Spectrograph on the 4.2-m William Herschel Telescope at the Observatorio del Roque de los Muchachos. It is concluded that SN1987L was a type Ia supernova, and approximately 100 days post maximum at the time of the observation.
