Piascik (Liverpool JMU) report on behalf\nof a larger collaboration:\n\nWe report Liverpool Telescope (La Palma) observations of iPTF-15dld and iPTF-15dni.\n\nSPRAT Spectroscopy and IO:O broad band optical photometry of iPTF-15dld was obtained on the\nnight of 2015-11-06. ��Interpolating over the host galaxy emission lines in the spectrum reveals\na continuum with broad emission features. ��With the data to hand we are\nnot confident in subtraction of the host galaxy continuum from that of the transient. ��The\nspectrum is broadly consistent with the identification made as a Type Ic broad line\nsupernova in GCN18632 but we are not able to constrain the redshift or age. ��Depending\non observation priorities we may schedule some further spectroscopy and photometry\nat later times.\n\nSPRAT Spectroscopy and IO:O redshifted H-alpha optical imaging of iPTF-15dni\nwas obtained on the night of 2015-11-05. ��Comparison of the spectrum with our\nearlier spectrum obtained on 2015-10-28 and reported in GCN18549 shows no\nsignificant change in the H-alpha emission line. ��Our H-alpha images show the galaxy\nhas many apparent star forming regions, although we can not resolve the location of the��\ntransient in H-alpha from the galaxy core without a reference image at this time. ����\nDepending on observation priorities we may schedule some further spectroscopy��\nand photometry at later times.\n\nDisclaimerNone",
