Therefore, it is possible that this is a Galactic X-ray burster, as noted by Palmer et al. (GCN 5208). If at a distance of 8 kpc, for example, its 15-150 keV fluence in the BAT of 1.8x10^-7 erg/cm2 (Palmer et al., GCN 5208) corresponds to an average luminosity of 1.1x10^38 erg/s in this band over the 13 s duration of the burst, and its 0.2-12 keV luminosity seen by XMM was 5.3x10^32 erg/s, within the range of quiescent LMXBs (e.g., Tomsick et al. 2004, ApJ, 610, 933).
