The visit planner cannot be run on them according to the error message. This target is not used in this proposal. If the target coordinates are not known to 0.4" (or better), an ACQ/SEARCH should precede the ACQ/IMAGE. INEFFICIENT ORDERING OF FP-POS POSITIONS INEFFICIENT ORDERING OF FP-POS POSITIONS Changed COS acquisition to NUV/ACQ with MIRRORB. Also reduced acquisiton exposure time to 30 seconds. -1949779125 ----- Attempting Submission 1 (Tue Jul 19 06:53:03 GMT 2016) ----- ----- Attempting Submission 2 (Sat Jun 10 17:06:29 GMT 2017) ----- ----- Attempting Submission 3 (Tue Jun 13 22:17:55 GMT 2017) ----- It is not possible to evently split the 4 COS positions in 3 orbits, therefore we choose to split the first orbit into 4 parts and the next two orbits into two parts each. This results in the inefficient FP-POS warnings. Far UV Spectroscopy of Superluminous Supernovae Optical transient searches have yielded a diverse sample of supernovae with peak luminosities 10-100 times greater than common events. These superluminous supernovae (SLSN) have been shown to be especially UV bright, which make these objects ripe for discovery at high redshifts. Indeed, archival searches have already identified SLSN out to z=3.9 and the first dedicated searches for these events at z>3 are now underway. However, there is a dearth of rest-frame, far-UV (FUV; <1800 A) spectra of SLSN available to enable classification of these high redshift discoveries. FUV comparison spectra from optically confirmed SLSN are needed to rule out contaminating sources, such as AGN and tidal disruption events. These spectra will also provide a new window on the physical nature of SLSN, which remains a source of debate. Here we propose to more than double the entire sample SLSN with rest-frame FUV spectra. This sample will enable the first test of whether these transients can accurately be classified through only their FUV spectra. This proposal is for UV spectroscopy of four superluminous supernovae to be found in Cycle 24. Two of these targets will be at low redshifts (z<0.4) and the other two will be at moderate redshifts (0.6 < z < 0.8). For each low-redshift target we request both COS/G140L and STIS/G230L observations. These observations require fast turn around (<10 days from activation), and should be considered disruptive ToOs. The other two, moderate-redshift targets will also be ToO targets, but these will be non-disruptive. For these, we request WFC3 G280 UV grism observations.
