Abstract SN1978K, in the barred galaxy NGC 1313, is the ONLY example of a very young supernova remnant of KNOWN age which is X-ray bright. The X-rays likely arise from the blast wave encountering the circumstellar medium. We propose to study the ultraviolet line emission from this remnant, which in such a young remnant, should be exceedingly rich, especially in [Fe II] lines. Other lines give additional density and abundance diagnostics. The UV spectrum is expected to evolve rapidly over the next few years. We hope to study the age-dependent development of the remnant in an external galaxy. SN1987A in the LMC and SN1993J in M81 will undergo the same phenomenon about a decade or so from now. A study of SN1978K now will shed light on issues to be resolved with observations of SN1987A and SN1993J. ------------------------------------------------------------------------------------ Observations Description ------------------------ Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- This program is a repeat for failure of program 5363. ------------------------------------------------------------------------------------ Data Distribution Media: 8MM Blocking Factor: 10 Ship To: PI_Address Ship Via: UPS Email: , ------------------------------------------------------------------------------------ 6341( 9) - 04/22/96 15:54 - [ 2] TARGET LIST a) Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC1313- EXT-MEDIUM,SNR,EXT- RA=3H 17M 38.6S +/- 0.168S,DEC=- J2000 V = V = 18.7 031738- STAR,SUPERNOVA TYPE II 66D 33' 4.6" +/- 1.00" 456.0 F-CONT(1690.0)=26.0+/-1.0e-16 663304-POS1 B-V = 6.0e-1 E(B-V) = 10.0e-3 Comments: V OBTAINED 1992 JANUARY; DECLINE SLOW.
