Greiner (all MPE Garching) report on behalf\nof the GROND team: \n\nWe present further analysis of the GROND observations of GRB 151112A \n(Swift trigger 663179; Malesani et al., GCN #18588; Knust et al. GCN\n#18595). \n\nAfter correcting for the galactic foreground E(B-V)=0.01 mag and \nfitting a power-law model to the 7-channel GROND SED from the first\nnight, \nwe derive a photometric redshift of z = 4.1 +/- 0.3, according to the\ng'- and r'-band \ndropouts with g'-r' > 1.5 mag and r'-i' = 0.9 mag. \n\nBased on the observed decay between the first and the second night we\npredict an \ni'-band magnitude of ~24 mag for the coming night.",
