Morii (ISM) \nreport on behalf of the MAXI team:\n\nThe MAXI/GSC nova alert system triggered a bright uncatalogued X-ray transient source at\n16:00:50 UT on 7 September 2015. Assuming that the source flux was constant over the transit,\nwe obtain the source position at\n(R.A., Dec) = (224.845 deg, -47.592 deg) = (14 59 22, -47 35 31) (J2000)\nwith a 90% C.L. statistical error of 0.06 deg. \nThere is an additional systematic uncertainty of 0.1 deg (90% containment radius).\nThe X-ray flux averaged over the scan was 1464 +- 75 mCrab (4-10keV, 1 sigma error).\nThere was no significant excess flux in the previous transit at 14:28 UT on 7 September 2015\nwith an upper limit of 20 mCrab.",
