PI: Matt Nicholl Harvard University Y CoI: Prof. Edo Berger Harvard University N CoI: Mr. Philip Cowperthwaite Harvard University N ------------------------------------------------------------------------------------ Abstract GRB170817A is the most nearby short GRB ever discovered. We detected an optical counterpart using DECam and propose to obtain a UV spectrum using STIS. ------------------------------------------------------------------------------------ Observations Description ------------------------ 1 orbit UV spectrum of LIGO BNS optical counterpart. Using STIS + G230L for wide wavelength coverage. ------------------------------------------------------------------------------------ 15382( 4) - 22-Aug-2017 12:33:20 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 BNS-MERGER EXT-STAR, GAMMA RAY RA=13H09M48.0900S +/- 1", J2000 V = 18 +/- 2 UVW1 ~ 17.7 BURSTER DEC=-23D22'53.35" +/- 1" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 2 GRB170817A EXT-STAR, GAMMA RAY RA=13H09M48.0900S +/- 1", J2000 V = 18 +/- 2 UVW1 ~ 17.7 BURSTER DEC=-23D22'53.35" +/- 1" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 15382( 4) - 22-Aug-2017 12:33:20 - [ 3] Visit: 01 Visit Requirements: On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 GRB170817A STIS/CCD ACQ 50CCD MIRROR 1 90 S (90 S) ------------------------------------------------------------------------------------------------------------------------------------ 2 GRB170817A STIS/NUV ACCUM 52X0.2 G230L 2376 1 2000 S -MAMA (2000 S) ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ GRB170817A 1 STIS/CCD ACQ 50CCD MIRROR none none none none 1 N/A GRB170817A 2 STIS/NUV ACCUM 52X0.2 G230L 2376 none none none none 1 N/A -MAMA 15382( 4) - 22-Aug-2017 12:33:20 - [ 4] Summary Form for Proposal 15382 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Apertures 50CCD, 52X0.2 ------------------------------------------------------------------------------------------------------------------------------------ Configurations STIS/CCD, STIS/NUV-MAMA ------------------------------------------------------------------------------------------------------------------------------------ Opmodes ACCUM, ACQ ------------------------------------------------------------------------------------------------------------------------------------ Optional Parameters ------------------------------------------------------------------------------------------------------------------------------------ Spectral Elements G230L, MIRROR ------------------------------------------------------------------------------------------------------------------------------------ Target Names GRB170817A ------------------------------------------------------------------------------------------------------------------------------------
