The 1032, 1038 Å emission lines of O vi were detected from SN 1987A by the FUSE satellite observations in 2000 and 2001. The lines are extremely narrow (fwhm < 35kms–1), indicating that the emission is not a by-product of the various circums tellar shock phenomena. The most likely origin of the O vi emission lines is recombination of the SN progenitor's red giant wind that was photoionized by the SN shock breakout on 1987 Feb 23.
