Greiner (MPE Garching), \nreport on behalf of the GROND team:\n\nGROND (Greiner et al. 2008, PASP 120, 405), the 7-channel imager mounted \nat the 2.2m ESO/MPI telescope on La Silla, started follow-up observations \nof GRB 100615A (D'Elia et al. 2010, GCN 10841) on June 15 at 2:05 UT \n(about 6 min after the trigger).\n\nWithin the 3.7 arcsec XRT error circle we do not find any afterglow \ncandidate. Preliminary measured upper limits based on an 8 min observing \nblock starting at 2:20 UT are (in the AB system, 3 sigma):\n\ng' > 24.2,\nr' > 23.9,\ni' > 22.9,\nz' > 22.5,\nJ  > 21.4,\nH  > 20.7,\nK  > 20.3,\n\nusing GROND zeropoints and the 2MASS catalog. This is in agreement with \nthe report by Dhillon et al. about the non-detection in the i' band (GCN \n10842).",
