Morii (ISM)\nreport on behalf of the MAXI team:\n\nThe MAXI/GSC nova alert system triggered a bright uncatalogued X-ray transient \nsource at 02:52:43 UT on on 2016 Feburary 6.\nAssuming that the source flux was constant over the transit,\nwe obtain the source position at\n(R.A., Dec) = (132.696 deg, -36.099 deg) = (08 50 47, -36 05 56) (J2000)\nwith a statistical 90% C.L. elliptical error region\nwith long and short radii of 0.33 deg and 0.3 deg, respectively.\nThe roll angle of long axis from the north direction is 23.0 deg counterclockwise.\nThere is an additional systematic uncertainty of 0.1 deg (90% containment radius).\nThe X-ray flux averaged over the scan was 125 +- 26 mCrab\n(4-10keV, 1 sigma error).\nWithout assumptions on the source constancy,we obtain a rectangular error\nbox for the transient source with the following corners:\n(R.A., Dec) = (132.055 deg, -35.576 deg) = (08 48 13, -35 34 32) (J2000)\n(R.A., Dec) = (132.787 deg, -35.291 deg) = (08 51 08, -35 17 28) (J2000)\n(R.A., Dec) = (133.399 deg, -36.778 deg) = (08 53 35, -36 46 40) (J2000)\n(R.A., Dec) = (132.642 deg, -37.044 deg) = (08 50 34, -37 02 39) (J2000)\nThere was no significant excess flux in the previous transit at UT 01:20\nand in the next transit at 04:25 UT with an upper limit of 20 mCrab for each.",
