MAXI/GSC detection of a new hard X-ray transient MAXI J0655-013

The MAXI/GSC nova alert system triggered on a bright uncatalogued X-ray transient source at 10:23 UT on June 18, 2022. Assuming that the source flux was constant over four transits from 10:23 to 15:02 on June 18, we obtain the source position at (R.A., Dec) = (103.865 deg, -1.398 deg) = (06 55 27, -01 23 52) (J2000) with a statistical 90% C.L. elliptical error region with long and short radii of 0.17 deg and 0.14 deg, respectively.
