Itoh (Miyazaki U.),\nK. Yamaoka (Nagoya U.) report on behalf of the MAXI team:\n\nWe report the MAXI/GSC detection of GRB 150206A (Hagen et al. GCN 17413) \nin the scan transit at 14:50 on 2015 February 06 UT, about 20 min after\nthe BAT trigger.\n\nAssuming that the source flux was constant over the transit,\nwe obtain the source position at\n(R.A., Dec) = (10.174 deg, -63.382 deg) = (00 40 41, -63 22 55) (J2000) \nwith a statistical 90% C.L. elliptical error region \nwith long and short radii of 0.34 deg and 0.28 deg respectively. \nThe roll angle of long axis from the north direction is 82.0 deg \ncounterclockwise. There is an additional systematic uncertainty of 0.1 deg \n(90% containment radius). \nThe position is consistent with that of GRB 150206A.\n\nThe X-ray flux averaged over the scan was 116 +- 25 mCrab (4-10keV, 1 sigma \nerror). \nThere was no significant excess flux in the previous transit at UT 13:21\nwith an upper limit of 20 mCrab.",
