Yamada (Miyazaki U.),\nK. Yamaoka (Nagoya U.) report on behalf of the MAXI team\n\nAt 2013-05-05T08:22:29 UT, the MAXI/GSC detected an uncatalogued X-ray\ntransient source. Assuming that the source flux was constant over the\ntransit, we obtain the source position at\n(R.A., Dec.) = (136.955 deg, 17.585 deg)= (09 07 49 , +17 35 05)(J2000)\nwith a 90% C.L. statistical error of 0.07 deg and an additional systematic\nuncertainty of 0.1 deg (90% containment radius).\n\nThe position and time are consistent with those of GRB 130505A (Cannizzo\net al, GCN #14563). The transit by MAXI occurred from\n2013-05-05T08:22:18 (=T0-10 s, where T0 is the Swift/BAT trigger time) to T0+40s.\nThe averaged X-ray flux was 3.17 +/- 0.21 Crab (2-20 keV).\nThe spectrum is fitted by a power-law model with a photon index of\n1.37 (-0.10/+0.10). There was no significant excess flux at the previous\ntransit at 2013/05/05 06:46 UT and at the next transit at 2013/05/05\n09:55 UT with an upper limit of 20 mCrab for each.",
