  "body": "We report the following spectroscopic observations and classifications\nof two of the EM candidates reported by Cenko et al. in GCN 18762. All\nobservations were obtained using the 2.0 metre Liverpool Telescope, La\nPalma by C.M. Copperwheat & I.A. Steele (Liverpool JMU) on behalf of a\nwider collaboration.\n\niPTF-15ffh was observed with the SPRAT spectrograph on 2016-01-02 at\n19:29UT. We previously observed this target in twilight and did not\ndetect the transient (GCN18791). The spectrum we obtained in this\nsecond visit does not contain any obvious features, and a visual\ninspection offers no clear classification. However, SNID (Blondin &\nTonry, 2007, ApJ, 666, 1024) provides a classification of a type Ia\nsupernova with z = 0.076 -/+ 0.007 at 22.2 days after peak. This\nredshift is consistent with the spectroscopic redshift of the assumed\nhost galaxy (0.06857).\n\niPTF-15fhp was observed with the SPRAT spectrograph on 2016-01-02 at\n23:31UT. In GCN18807 we reported a previous epoch of observation for\nthis transient in which we obtained a poor quality spectrum which SNID\nclassified as a type Ia supernova approximately one week before peak.\nIn this second visit the brightness of the target has not increased,\nand so we would rule out this initial tentative classification. Again,\na classification is not obvious from a visual inspection of this\nsecond epoch, but SNID reports this object is a type Ia supernova with\nz=0.130 -/+ 0.007 at 4.1 days after peak.\n\n\n-- \n------------------------------------------------------\nC.M.Copperwheat\nAstrophysics Research Institute,\nLiverpool John Moores University\n------------------------------------------------------\nhttp://telescope.livjm.ac.uk\n------------------------------------------------------\nEmail: c.m.copperwheat@ljmu.ac.uk\nTel: +44 (0)151 231 2914\nFax: +44 (0)151 231 2921\n------------------------------------------------------",
