Nicuesa Guelbenzu (all \nTautenburg) report:\n\nWe continued observing the field of GRB 200412B (Fermi GBM team, GCN \n27547) with the Tautenburg 1.34m Schmidt telescope equipped with the \nTAUKAM 6k x 6k CCD camera and the wide V-band filter (VB; Stecklum et al., \nGCN 27567).\n\nFor the optical transient (Lipunov et al., GCN 27555, 27556) at a mean \ntime APR 13, 21:08:59 UT (1.500 days post burst) we measure VB = 20.27 +/- \n0.03. Compared to our 1st-epoch observations (dt=0.51 days; Stecklum et \nal., GCN 27567) this provides a decay slope of alpha = 1.58 (F\\nu \\propto \nt**(-\\alpha)), in agreement with the results reported by Xin et al. (GCN \n27571) and Belkin et al. (GCN 27574).",
