GCN 19075) using the \n2.56m Nordic Optical Telescope (NOT) equipped with the ALFOSC camera. \nObservations started at 23:31:27 UT on 2016-02-25 (i.e., 8.56 hr \npost-burst) and 9x200s exposures were obtained in the Sloan r- and \ni-band, respectively.\n\nThe optical afterglow is detected at the WHT position (Wiersema et al., \nGCN 19082) and presumably also the MITSuME position (Yoshii et al. GCN \n19080). We measured m(r)=23.25 +/- 0.15 at 8.86 hr post-burst and m(i) = \n22.55 +/- 0.07 at 9.48 hr post-burst, calibrated with nearby SDSS stars.",
