GRB 240128A: MAXI/GSC detection
Abstract
The MAXI/GSC nova alert system triggered on an uncatalogued X-ray transient source at 15:14:03 UT on January 28, 2024. Because our localization program did not run, we can not provide a precise error region. The source position determined with the nova alert system (Negoro et al. 2016) is (R.A., Dec) = (139.846 deg, -5.053 deg) = (09 19 23.04, -05 03 10.8) (J2000) with an uncertainty of more than 30 arc-min. The burst duration is about 30 sec, and the averaged X-ray flux in the 2-10 keV range was about 600 mCrab. This event was also detected by INTEGRAL SPI-ACS. There was no significant excess flux in the previous transit at 13:37 UT with an upper limit of 20 mCrab.
