Swift reports the detection of a new transient source Swift J2058.4+0516
Abstract
The hard X-ray transient monitor of the Swift Burst Alert Telescope (BAT) has detected a previously unknown transient source. Swift X-Ray Telescope (XRT) observations have confirmed the detection and produced a refined position. The new source, Swift J2058.4+0516, was first detected by the BAT at a daily average rate of 0.0029 ± 0.0007 counts/sec/cm2 (15 mCrab) in the 15-50 keV band on 2011 May 18 (MJD 55699).
