Hearnshaw (Univ. of Christchurch) and A. J. Castro-\nTirado (IAA-CSIC), on behalf of a larger collaboration,\n\nreport:\n\n\"We have continued the BVRI optical monitoring of the proposed\noptical afterglow (Tristram et al. GCNC 6312) to GRB 070419B\n(Parson et al. GCNC 6305) with the 0.6m B&C telescope at the\nMt. John Observatory on Lake Tekapo. We confirm the detection\nin the VRI -bands and a derive a complex lightcurve (preliminary\nanalysis shows a steep decline up to T0 + 0.2 days and a plateau\nphase lasting until the end of our observations at T0 + 0.3 days\nwith R ~ 21.0).\n\nA more accurated astrometry (+/- 0.5\") yields:\n\nAR(2000): 21:02:49.78\nDec(2000): -31:15:48.8\n\nA finding chart is posted at:\nhttp://www.iaa.es/~deugarte/GRBs/070419B/GRB070419B.gif\n\nSpectroscopic and photometric observations are encouraged.\"\n\nThis message can be quoted.",
