Ludwig (TLS Tautenburg) report:\n\nWe began observations of GRB 150213B (Swift trigger 631051, Pagani et al.,\nGCN 17464) with the 1.34m Tautenburg Schmidt telescope about 80 min after\nthe GRB, at airmass 2.9.\n\nAt the UVOT position given by Pagani et al., we detect the optical\nafterglow in multiple Rc band exposures of 600 sec exposure time each. Due\nto the PSF wings of a nearby bright star, no magnitude can be determined\nat this time, but the source has clearly faded compared to the early Swift\ndetection.\n\nObservations are ongoing.",
