MAXI/GSC detection of a hard X-ray transient MAXI J0206-749 near the SMC
Abstract
The MAXI/GSC nova alert system triggered on an uncatalogued X-ray transient source at 16:31 UT on November 20, 2019. Assuming that the source flux was constant over 13 scan transits from 21:58 on November 19 to 22:43 on November 20, we obtain the source position at (R.A., Dec) = (31.664 deg, -74.930 deg) = (02 06 39, -74 55 49) (J2000) with a 90% C.L. statistical error of 0.47 deg and an additional systematic uncertainty of 0.1 deg (90% containment radius).
