MAXI/GSC detection of a possible new X-ray nova MAXI J1621-501 on the galactic plane
Abstract
The MAXI/GSC nova alert system triggered on a bright uncatalogued X-ray transient source at 05:45 UT on 2017 October 19. Using GSC camera GSC_5 data of 4 scan transits from 04:12 to 08:50, we obtain the source position at (R.A., Dec) = (245.260 deg, -50.185 deg) = (16 21 02, -50 11 06) (J2000) with a statistical 90% C.L. elliptical error region with long and short radii of 0.23 deg and 0.22 deg, respectively.
