MAXI GSC and SSC detection of a soft X-ray transient near SMC: XRF 111111A / MAXI J0158-744
Abstract
MAXI/GSC triggered a bright uncatalogued X-ray transient source at UT 2011-11-11T05:05:59. The source is extremely soft and most of the flux is emitted below 4keV. Assuming that the source flux was constant over the transit, we obtain the source position at
(R.A., Dec) = (+29.5 deg, -74.4 deg) = (01 58 03, -74 24 01)(J2000)
with a 90% C.L. statistical error of 0.42 deg. There is additional systematic uncertainty of 0.1 deg (90% containment radius).
