GCN Circular 8826
F. Olivares (MPE Garching), A. Rossi (Tautenburg Obs.), A. Kupcu Yoldas (ESO), J. Greiner, and A. Yoldas (both MPE Garching) report on behalf of the GROND team: We observed the field of the possible GRB 090118 (Swift BATSS trigger, Copete et al. GCN #8825) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2m MPI/ESO telescope at La Silla (Chile). Observations started at 00:55 UT, about 11 hrs after the GRB. Comparison to the Digital Sky Survey reveals no new sources within the Swift/BAT error circle (Copete et al. GCN #8825). Co-added images of the first 8 minutes yield the following 5-sigma limits (in AB magnitudes): r' > 23.2 i' > 22.5 The magnitudes are calibrated against SDSS.
