Miscellaneous :
Markwardt et al. 2008 ATel 1709:
  • Outburst seen by RXTE in Feb-March 2004
  • New outburst started in Sept 08, seen with RXTE and Swift
  • BAT, PCA and BAT IBIS sources are consistent => XTE source and IGR one are the same
Shaw et al. 2008 ATel 1711:
  • Source also detected by IBIS on 2008 Sept. 5
  • Source flux a factor of 2 higher than the flux seen with BAT
Chelovekov & Grebenev 2010:
  • Details on source discovery and subsequent INTEGRAL observations (2004-2009)
  • 2 hard X-ray flares and 1 type I X-ray burst recorded.
  • Flare spectrum => power law with Γ=1.8-2.0, or kt=90-140 keV bremsstrahlung
  • 18-40 keV flux 3-σ upper limit 0.15 mCrab in quiescence
Curran et al. 2011:
  • IR and Optical identifications of counterpart
  • R=21.5, I=20.0, J=18.3, H>18, Ks>18
  • SED consistent with stellar-like black body
