We propose to study the ultraviolet line line_5: emission from this remnant, which in such a young remnant, should line_6: be exceedingly rich, especially in \[Fe II\] lines. Other lines give line_7: additional density and abundance diagnostics. The UV spectrum is line_8: expected to evolve rapidly over the next few years. We hope to study line_9: the age-dependent development of the remnant in an external galaxy. line_10: SN1987A in the LMC and SN1993J in M81 will undergo the same line_11: phenomenon about a decade or so from now. A study of SN1978K now line_12: will shed light on issues to be resolved with observations of SN1987A line_13: and SN1993J. ! ! end of abstract general_form_proposers: lname: SCHLEGEL fname: ERIC mi: M inst: 3650 country: USA ! lname: COLBERT fname: ED inst: 2620 country: USA ! lname: PETRE fname: ROBERT inst: 2856 country: USA ! lname: RYDER fname: STUART inst: 4140 country: AUSTRALIA ! lname: STAVELEY-SMITH fname: LISTER inst: 4125 country: AUSTRALIA ! lname: DOPITA fname: MICHAEL inst: 4140 country: AUSTRALIA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: We request blue and red FOS spectra of the target, SN1978K, line_2: and its immediate surrounding H II region. This requires a line_3: pointing at SN1978K to obtain the blue and red FOS spectra, line_4: and an offset to obtain the H II region. A finding chart line_5: will be available in the October (10?) 1993 Ap.J. Based on line_6: the finding chart, the direction of the offset does not make line_7: a difference to the science. ! question: 4 section: 1 line_1: HST is needed for the ultraviolet capabilities unavailable from the line_2: ground. IUE is sufficiently small that even a very long exposure line_3: (15-20 hours) produces a low signal/noise (~3-5) spectrum. We have line_4: argued in the justification that a good quality spectrum (signal/noise line_5: > 10) pays larger science dividends than a low signal/noise spectrum. line_6: IUE is simply too small to deliver a reasonable signal/noise spectrum. ! question: 5 section: 1 line_1: None needed. ! question: 6 section: 1 line_1: None needed. ! ! question: 8 section: 1 line_1: None needed. ! question: 9 section: 1 line_1: P2266: "Post Asymptotic Giant Branch Evolution in the Magellanic line_2: Clouds"; M.

He has a SPARC II which will be used in the line_5: modelling.
