Swift observes an outburst from the Supergiant Fast X-ray Transient SAX J1818.6-1703
Abstract
The Swift/BAT caught a new outburst from the Supergiant Fast X- ray Transient SAX J1818.6-1703 on May 6 at 14:02:11 UT. The time-averaged spectrum for the BAT data from T+0.0 to T+64.0 s is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 3.34+/-0.62. The fluence in the 15-150 keV band is (2.1+/-0.6)E-07 erg/cm2. The averaged BAT light curve shows the source flux peaking between T-123 and T+69 at 0.05 +/- 0.006 ct/s/cm2 and falling to 0.03+/-0.005 ct/s/cm2 between T +309 and T+501.
