Scientific paper

The extraordinary brightness of supernova 1987A has been used to study the intergalactic medium toward the supernova. High-resolution spectra with high SNRs were obtained which sample the galactic disk and halo, interstellar gas in the LMC, and the intervening medium. Thirty-five distinct components have been clearly identified, probably located between the Galaxy and the LMC and showing low dust content. Sodium/calcium abundance radios are sued to infer the physical parameters of the clouds. The results suggest that the Magellanic Stream has a nearly solar abundance in the detected elements.
