Szokoly \n(Eoetvoes Univ., Budapest and MPE Garching) (all others MPE Garching) report \non behalf of the GROND team:\n\nWe observed the field of GRB 080325 (Swift trigger 307604; L. Vetere et al., \nGCN #7512) simultaneously in g', r', i', z', J, H and K with GROND (Greiner \net al. 2008, PASP) mounted at the 2.2m ESO/MPI telescope at La Silla \nObservatory (Chile).\n\nObservations started at 09:50 UT on March 25th, 2008, about 5.7 hrs after the \nGRB trigger. We obtained 20 mins of total integration time in J, H and K \nduring morning twilight.\n\nWe do not detect any new source within the 2.6'' enhanced Swift-XRT error \ncircle reported by J. Osborne et al. (GCN #7513) to the following 3-sigma \nupper limits:\n\nJ > 20.4, H > 19.4 and K > 19.0.\n\nWe also detect the afterglow candidate, about 6\" south of the centre of the \nenhanced Swift-XRT error circle, reported by A. Updike et al. (GCN #7515) to \nfollowing magnitude:\n\nJ = 18.60 +/- 0.06,\n\ncalibrated against 2MASS catalogue stars.",
