Sugizaki (NAOC)\n\nreport on behalf of the MAXI team:\nThe MAXI/GSC nova alert system triggered a bright uncatalogued X-ray \ntransient source at 17:33:25 UT on 2022 July 6 at\n(R.A., Dec) = (0.219 deg, -16.471 deg) (J2000)\nThis position was consistent with GRB 220607A (GCN #32329) and the scan transit\nwas 5051 sec after the BAT trigger time (T0).\nThe scan was not completed because the GSC HV turned off due to the high \nlatitude constraint. The preliminary observed flux was about 200 mCrab in \nthe 2 - 10 keV band.\nThe transient was also observed at the next scan transit (17:53, T0+6260s) and \nthe flux decayed to about 60 mCrab in the same energy band.\nWe note that Swift/XRT also detected bright X-ray flare around T0+5400s.\nThere was no significant excess flux in the previous transit at 16:00 UT\nand in the third transit at 19:26 UT with an upper limit of 20 mCrab for each.\nSince the X-ray flaring activity of this GRB was unusual, we encourage \nmulti-wavelength observations.",
