  "body": "K. Torii (Osaka U.) reports\n\n \"The error region of GRB 050319 (GCN 3117) was observed by the \nART 14-inch telescope. BVRcIc imaging started at 2005 March 19, 11:24\nUT and 60-s exposure in each filter was repeated.\n\n By stacking twenty Rc and twenty Ic frames obtained between 11:36 UT\nand 13:05 UT (Mean Epoch 12:20 UT), we note an enhancement of\n2.3-sigma level at the position of the optical afterglow (GCN\n3116). The enhancement in the stacked frame corresponds to 19.6 mag\nwith reference to USNO-A2.0 red magnitude.\n\n Combining this magnitude and those reported in GCN 3116 and GCN 3120,\nthe early optical afterglow of GRB 050319 decays with relatively\nshallow power-law index of t^(-0.6).\"",
