Szokoly (Budapest Univ.) report for the\nGROND team:\n\nWe observed the field of GRB 080207 detected by Swift/BAT (Racusin et al.\n2008, GCN 7264)  simultaneously in grizJHK with GROND (Greiner et al. 2008,\nastro-ph/0801.4801), mounted at the 2.2m MPI/ESO telescope at La Silla (Chile).\nObservations started on Feb. 08, at 06:35 UT, about 9 hrs after the GRB,\nunder poor conditions (particularly high humidity and airmass of 1.7-1.34).\n\nNo source is detected within the 3-sigma XRT error circle (Beardmore et al.\n2008, GCN 7265). Comparison of the co-added images (with 3440 sec effective\nexposure time in griz and 2400 seconds in JHK) to the Digital Sky Survey \nand 2MASS yields the following 3-sigma upper limits:\ng' > 23.9,  r' > 23.8,  i' > 23.5,  z' > 22.8,  J > 21.0,  H > 19.7,  K > 19.0.",
