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 00:43:52 UT on 2016 January 1.\nAssuming that the source flux was constant over the transit,\nwe obtain the source position at\n(R.A., Dec) = (219.733 deg, -13.823 deg) = (14 38 55, -13 49 22) (J2000) \nwith a statistical 90% C.L. elliptical error region \nwith long and short radii of 0.10 deg and 0.09 deg, respectively. \nThe roll angle of long axis from the north direction is 150.0 deg counterclockwise. \nThere is an additional systematic uncertainty of 0.1 deg (90% containment radius).\nThe X-ray flux averaged over the scan was 1543 +- 100 mCrab (4-10keV, 1 sigma error).\n\nWithout assumptions on the source constancy,we obtain a rectangular error\nbox for the transient source with the following corners:\n(R.A., Dec) = (219.635 deg, -14.100 deg) = (14 38 32, -14 05 59) (J2000)\n(R.A., Dec) = (219.486 deg, -13.957 deg) = (14 37 56, -13 57 24) (J2000)\n(R.A., Dec) = (220.532 deg, -12.732 deg) = (14 42 07, -12 43 54) (J2000)\n(R.A., Dec) = (220.677 deg, -12.878 deg) = (14 42 42, -12 52 39) (J2000)\nThere was no significant excess flux in the previous transit at 23:11 UT on 2015 December 31\nwith an upper limit of 20 mCrab for each.",
