Preliminary photometry\nresults are as follows\n\nAll combined images\n(Total exposure time: 154 min, 2013-05-15 01:26 - 04:41)\n J = 20.1 \u001b$B!^\u001b(B 0.2\n H = 18.6 \u001b$B!^\u001b(B 0.2\n Ks =18.7 \u001b$B!^\u001b(B 0.3\n\nFirst 120 images\n(Total exposure time: 60 min, 2013-05-15 01:26 - 2:45)\n J = 19.4 \u001b$B!^\u001b(B 0.2\n H = 18.9 \u001b$B!^\u001b(B 0.2\n Ks: Non detection\n\nThese magnitudes are in the Vega system and not corrected for\nGalactic extinction in the direction of the GRB.",
