This event should\ncorrespond to a GRB detected by Fermi-GBM, INTEGRAL SPI-ACS\nandKonus-Wind.\n\nThe location of the source derived from the GSC data is \n(R.A.,Dec.)=(226.81 deg, -21.79 deg)=(15:07:14.40, -21:47:24.0)(J2000) \nwith an uncertainty of about 0.5 degree.  This is consistent with that\nreported by Gruber (GCNC10187) within an error.\n\nThe GSC FOV scanned over the source from 04:34:56 (UT) (16 seconds\nafter the GBM trigger) for about 40 seconds.  The average X-ray flux\nover the observation is 4.9x10^-8 erg/cm2/s in 3-15 keV.  Significant\nintensity variation was clearly seen in the light curve. \n\nMAXI is currently under the commissioning phase and the systematic\nuncertainty in localization will be significantly improved with the\nprogress of the alignment calibration.\nThis message may be citable.",
