Yuan (Australian National University), report on behalf of the\nROTSE collaboration: \n\nFurther analysis of ROTSE-IIIb data revealed that the OT of GRB 130215A\n(Swift trigger 548760; D'Elia et al., GCN 14204; Zheng et al GCN 14205;\nLaCluyze et al. 14206) peaked around 750s after the burst, followed with\na single power-law decay with index alpha = -1.24 up to ~4ks after the\nburst. Observation is on going.\n \nInterestingly the GRB is also triggered by Fermi-GBM (trigger\n382584689). The GBM trigger arrived ~600s earlier than Swift-BAT trigger\nand ROTSE-IIIb responded to GBM trigger at first. A 4x4 tiling follow-up\nmode was performed before BAT-trigger interrupted it and a total of 22\nimages were obtained to GBM trigger. Unfortunately, our effort of the\ntiling follow-up still didn't cover the OT location in these images\nsince the GBM trigger is about 3.78 degree away, just a bit away from\none of the corner.",
