HST is the essential tool for spatially-resolved observations of SN1987A's many components. A violent encounter is now underway between the fastest-moving debris and the circumstellar ring: the shock excites "hotspots." The optical, infrared and X-ray fluxes are rising rapidly on 6- month time scales: we have organized HST, SPITZER, and CHANDRA observations to understand these regions. In Cycle 16, the separate hotspots may begin to fuse as the shock fully enters the circumstellar ring. Photons from these shocks will excite previously invisible gas outside the ring, revealing the true extent of the mass loss that preceded the explosion of Sanduleak -69 202. The inner debris of the explosion, excited by radioactive isotopes from the explosion, is now resolved and seen to be aspherical, providing direct evidence on the asymmetry of the explosion. Questions about SN 1987A remain unanswered. How did the enigmatic three rings form? Precisely what happened during the core collapse and bounce? Is a black hole or a neutron star left behind? The rich and deep data set from SAINTS will help answer these central questions of supernova science. ------------------------------------------------------------------------------------ Observations Description ------------------------ 4 orbits for sn1987a Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ 11181( 2) - 05/02/07 07:29 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SN1987A EXT-STAR, SUPERNOVA RA=05H35M28.1100S +/- 0.1", J2000 V = 23.0 DEC=-69D16'10.85" +/- 0.1" Reference Frame: ICRS 11181( 2) - 05/02/07 07:29 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFPC2-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.559017 Line_Spacing 0.559017 Coordinate_Frame POS-TARG Pattern_Orient 26.56505 Angle_Between_Sides 143.130102 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 11181( 2) - 05/02/07 07:29 - [ 5] Visit: 01 Visit Priority: Visit Requirements: ORIENT 70.0D TO 90.0 D;
