Within errors this position coincides with the afterglow \ncandidate (Perley, GCB 14753) and the error circle of XRT reported by \nMelandri et al. (GCN 14752). This object is not detected in our later \ncombined images and can be the afterglow of GRB 130604A. Preliminary \nphotometry  of our images obtained in clear filter is based  on USNO-B1.0 \n(R2)  nearby  stars:\n\nUT start,      T0+          Exposure,  OT,                 UL (3 sigma)\n                   mid,days  s\n\n06:56:11       0.0019    3x30           n/d                  19.7\n06:56:11       0.0035    9x30           20.3 +/- 0.3      20.0\n06:56:11       0.0091  30x30           n/d                  20.5\n06:56:11       0.0171  60x30           n/d                  20.8\n\nFinding chart can be found at \nhttp://grb.rssi.ru/GRB130604A/GRB130604A_ISON_NM_9x30.png",
