Pandey (ARIES, Nainital,\nIndia, on behalf of larger Indian GRB collaboration)\n\nWe started to observe the GRB 120404A field (Swift trigger 519380, Stratta\net al., GCN Circ. 13208) with the 1.04m telescope at ARIES, Nainital\nstarting 2012-04-04 19:18:43 (UT). Several images in R_c and I_c pass-bands\nwere obtained.\n\nThe optical afterglow  candidate (Stratta et al., GCN Circ. 13208,\nGuidorzi et al. GCN Circ. 13209) was clearly detected in our frames.\nThe preliminary photometry of co-added R_c (300sec x 4) and I_c\n(300sec x 3) frames yield the following magnitudes.\n\n...............................................................\nTime (MID-UT)     Exp (sec)          Filter        Magnitude\n...............................................................\n19:39:40           1200                R_c       20.6 +/- 0.14\n19:51:22            900                I_c       19.7 +/- 0.12\n...............................................................\n\nThe nearby USNO stars have been used for calibration.\n\nThis massage may be cited.",
