These superluminous supernovae have been shown to be especially UV bright, which make these objects ripe for discovery at high redshifts. However, there is a dearth of rest-frame, far-UV (FUV; lambda < 1700A) spectra of superluminous supernovae available to enable classification of these high redshift discoveries. Here we request second-epoch COS spectroscopy of the recently discovered SN~2018bsz. These data will set a local reference point to compare against high redshift SLSN candidates from JWST. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal is for COS/FUV spectroscopy of SN2018bsz. ------------------------------------------------------------------------------------ 15489( 3) - 18-Jun-2018 19:20:15 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SN2018BSZ EXT-STAR, SUPERNOVA RA=16H09M39.1100S +/- 0.2", J2000 V = 17 +/- 1.0 DEC=-32D03'45.63" +/- 0.2" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 15489( 3) - 18-Jun-2018 19:20:15 - [ 3] Visit: 01 (SN2018bsz-COS) Visit Requirements: BETWEEN 17-JUL-2018 AND 25-JUL-2018 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 SN2018BSZ COS/NUV ACQ/IMA PSA MIRRORA 1 30 S (30 GE S) ------------------------------------------------------------------------------------------------------------------------------------ 2 SN2018BSZ COS/FUV TIME-TA PSA G140L 1105 FLASH=YES, BUFFER-TIME=6000, 1 2500 S G FP-POS=ALL see below (11387 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 | ------------------------------------------------------------------------------------------------------------------------------------ SN2018BSZ 1 COS/NUV ACQ/IMA PSA MIRRORA none none none none 1 N/A GE SN2018BSZ 2 COS/FUV TIME-TA PSA G140L 1105 none none none 1 1 2525.0 S G SN2018BSZ 2 COS/FUV TIME-TA PSA G140L 1105 none none none 2 2 2954.0 S G SN2018BSZ 2 COS/FUV TIME-TA PSA G140L 1105 none none none 3 3 2954.0 S G SN2018BSZ 2 COS/FUV TIME-TA PSA G140L 1105 none none none 4 4 2954.0 S G 15489( 3) - 18-Jun-2018 19:20:15 - [ 4] Summary Form for Proposal 15489 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Apertures PSA ------------------------------------------------------------------------------------------------------------------------------------ Configurations COS/FUV, COS/NUV ------------------------------------------------------------------------------------------------------------------------------------ Opmodes ACQ/IMAGE, TIME-TAG ------------------------------------------------------------------------------------------------------------------------------------ Optional Parameters BUFFER-TIME=6000, FLASH=YES, FP-POS=ALL ------------------------------------------------------------------------------------------------------------------------------------ Special Requirements BETWEEN 17-JUL-2018 AND 25-JUL-2018 ------------------------------------------------------------------------------------------------------------------------------------ Spectral Elements G140L, MIRRORA ------------------------------------------------------------------------------------------------------------------------------------ Target Names SN2018BSZ ------------------------------------------------------------------------------------------------------------------------------------
