Tanga (all MPE Garching) report on behalf of the GROND team:\n\nWe re-observed the field of GRB 140302A (Swift trigger 589685; Pagani et\nal., GCN #15901) simultaneously in g'r'i'z'JHK with GROND (Greiner et al.\n2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at La Silla\nObservatory (Chile).\n\nObservations started at 07:18 UT on 4th March 2014, 2 days after the GRB\ntrigger. They were performed at an average seeing of 1.1\" and at an\naverage airmass of 1.3.\n\nWe no longer detect the source noted in our previous observations (Elliott\net al.; GCN #15903) that had a magnitude of r' = 23.7 +/- 0.2 mag. For a\ntotal exposure of 1.2 hours we obtain an upper limit (AB) of r' > 25.2 mag\nand confirm this as the afterglow of GRB 140302A.\n\nThe given limit is derived based on calibrating the image against GROND\nzeropoints and is not corrected for the Galactic foreground extinction\ncorresponding to a reddening of E(B-V)= 0.52 mag in the direction of the\nburst (Schlegel et al. 1998).",
