Miscellaneous :
Sguera et al. 2007, A&A :
  • INTEGRAL/IBIS analysis of the only flare ever detected.
  • Source active during 3.5 hours and showed a short and bright 1.5 hour flare
  • 20-300 keV peak flux was 80 mCrab.
  • The 17-300 keV IBIS spectrum does not show any break up to 300 keV
  • The 17-300 keV IBIS spectrum well represented by a black body of 1 keV with a radius of 7.7 km and a hard power law with photon index 0.55.
  • Some spectral evolution seen on a scw basis.
  • Suggest source is an AXP, other types not completely ruled out
