Takagi (Univ. of Hyogo)\nreport on behalf of Nayuta team:\n\nWe performed low resolution ( R ~ 500) optical spectroscopic observations\nof a source on the position of GRB 130427A (Masell et al., GCNC 14448)\nwith MALLS attached to the Nayuta 2-m telescope at the Nishi-Harima\nAstronomical Observatory.\n\nThe observations were conducted from 2013-04-27 12:48 UT to 2013-04-27\n22 : 09 UT (from ~5.1 h to ~ 5.4 h after the burst).\n\nThe resulting spectrum ( S/N ~ 5) shows a feature less continuum light\nwithout any emission nor absorption line features in the wavelength\nrange between 450 nm and 680 nm.\n\n[GCN OPS NOTE(30apr13): Per operator, I have corrected a mistake I made \nin assigning the affiliation for this submitor.]",
