Kasliwal (Caltech)\n\nreport on behalf of the GROWTH (Global Relay of Observatories Watching\nTransients Happen) collaboration\n\nOn UT 2017-03-16, we spectroscopically classified the following ATLAS\noptical transient candidates (LVC GCN#20881) using the Double Beam\nSpectrograph (Oke & Gunn 1982) on the Palomar 200-inch Hale Telescope. All\nspectra were reduced using the pyraf-dbsp pipeline (Bellm & Sesar 2016) and\nspectral matching done using SNID and Superfit.\n\nName, Redshift, Classification, Notes\nATLAS17byq, z=0.045, SN Ia, best match is SN 1994D at -3 days\nATLAS17byo, z=0.03, SN Ia, best match is SN 2000dn at peak\nATLAS17cgg, z=0.02, SN IIn, best match is SN 1998S at -12 days",
