Scientific paper

This is the final report on project NAG5-2610, 'IUE Observations of B Supergiants in the Small Magellanic Cloud'. We have observed over 70 B supergiants in the Small Magellanic Cloud with the IUE satellite, using the low dispersion mode. These stars were chosen because they resemble the precursor star to SN 1987a, and we saw the need for a data base in the continuing effort to understand why the precursor star was a blue, not a red supergiant. The observations have all been reduced and made into an atlas, and efforts to understand the evolutionary history of stars in this part of the H-R diagram are underway.
