Abstract We are now underway in our intensive study of supernovae with HST. This long-term project promises to illuminate problems in stellar evolution, the mechanism of stellar explosion, nucleosynthesis, the energetics of interstellar gas, and the extragalactic distance scale. Initial observations, starting in the Spring of 1992, show that HST observations of SN 1987A are rich in content and that these high- minded goals can actually be achieved. Our HST observations of a new supernova, SN1992A, demonstrate that Target-of-Opportunity observations with HST are worth the effort. We were poised to observe SN 1993J in M81 and we obtained a beautiful UV/optical spectrum from an early epoch of this peculiar supernova. Our long-term plan is to continue the imaging and spectroscopy of SN 1987A, to obtain unprecedented late-time UV spectra of SN 1993J, and to realize the promise of our Cycle 1 proposal by following the late-time light curves of SN 1992A and SN 1993J. SN 1992A and SN 1993J demonstrated our ability to orchestrate observations from the ground, with IUE, and from HST to investigate important issues in supernova research. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. We will observe two different supernovae in this Cycle 4 program: SN 1993J and SN 1994I. The observations of SN 1993J in this program replace those of SN-1993J- OFFSET in program 5480. The observations of SN1994I supplement those in programs 5623 amd 5652. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. We have very good access to ground based facilities which are essential to getting the most out of our HST data. We have the ability to get spectra from the 1.5m at Mount Hopkins, and photometry from the 1.2m telescope there. We have regular assignments on the MMT and at the KPNO 2.1m that ensure we can get the observations of the supernovae when they are faint at age 1 year. We haveen listed the CTIO and Berkeley observers to the SINS team. They have been outstandingly effective observers of supernovae. ------------------------------------------------------------------------------------ 11. Address Information Name: ROBERT P.
