MAXI/GSC detection of a bright hard X-ray outburst probably from AX J1631.9-4752
Abstract
The MAXI/GSC nova alert system triggered on a bright hard X-ray transient source at 04:33 UT on December 21, 2018. Assuming that the source flux was constant over each scan transit at 04:33 and 06:06, we obtain the source position at (R.A., Dec) = (247.770 deg, -47.920 deg) = (16 31 04, -47 55 12) (J2000) with a statistical 90% C.L. elliptical error region with long and short radii of 0.17 deg and 0.17 deg, respectively.
