This is a continuation of our large, long-term project on supernovae, approved by the Cycle 4 TAC for Cycles 5 and 6. Supernovae create the chemical history of the Universe, energize the interstellar gas, and are central to efforts to measure the extragalactic distance scale. Our approach is intensive study of a few objects, such as SN 1987A, SN 1992A, SN 1993J in M81, and SN 1994I in M51, a Cycle 5 discovery, and a bright, new supernova to be discovered during Cycle 6. Our SN 1987A observations include images and spectra of the debris and the circumstellar rings. In our target-of-opportunity studies, we have used HST effectively to obtain unique UV spectra and images of supernovae in nearby galaxies. In Cycle 6 we will observe the continuing evolution of SN 1987A as radioactivity powers the expanding, resolved debris and as the inner and outer rings glow from recombination. Our Cycle 6 program will scrutinize the very late-time emission from three objects observed near maximum light: SN 1992A, SN 1993J, and our Cycle 5 target. Our most adventurous observation is the prompt study of a newly-discovered supernova during Cycle 6. We have not yet observed a classic SN II, or a member of the SN Ib class, two types which promise to be most interesting in the UV.
