Abstract
We further analyzed the outburst of the X-ray burster 1A 1246-588 recently detected with Swift on 2006 August 11 (GCN #5436, Romano et al. 2006). Swift XRT began observation 193s after the BAT trigger; the X-ray light curve was clearly fading during the first ~500s and after that, the source count rate remained constant. We extracted time-resolved energy spectra for the first 400s. The spectra can be fitted with an absorbed blackbody model with temperature decreasing from 0.82 keV for the first 50s to 0.65 keV for the last 100s.
