Kamble\n(University of Amsterdam) report on behalf of a larger collaboration:\n\n\"We observed the position of the GRB 090102 afterglow at 4.9 GHz with the\nWesterbork Synthesis Radio Telescope at January 8 18.88 UT to January 9\n6.86 UT, i.e. 6.66 - 7.16 days after the burst (GCN 8762).\nWe do not detect a radio source at the position of the optical counterpart\n(GCN 8766). The three-sigma rms noise in the map around that position is\n72 microJy per beam. The formal flux measurement for a point source at the\nposition of the optical counterpart is 12 +/- 24 microJy.\n\nWe would like to thank the WSRT staff for scheduling and obtaining these\nobservations.\"",
