Receipt: # 15489-1 ----- Attempting Submission 2 (Mon Jun 18 17:06:58 GMT 2018) ----- Optical transient searches have yielded a diverse sample of supernovae with peak luminosities 10-100 times greater than normal. 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. This proposal is for COS/FUV spectroscopy of SN2018bsz.
