Black hole binary (?) 17h 26m 49.28s -47o 38' 24.9" I band: Maitra et al. 2005 Atel 628
17h 26m 49.30s -47o 38' 25.5" Ks Band Steeghs et al. 2005 Atel 629
Miscellaneous :

Levine et al. Atel 623: RXTE/ASM Hardness ratios are very soft => suggests black hole binary with thermal spectrum
Maitra et al. Atel 628:
  • I=16.97 +/- 0.11
  • Finding Chart available here (courtesy D. Maitra et al.)
Steeghs et al. Atel 629:
  • Ks=16.2
  • Finding Chart available here (courtesy D. Steeghs et al.)
Tuerler et al. Atel 631:
  • Not detected above 10 keV with INTEGRAL
Kennea et al. Atel 632:
  • NH=4.8 x1021 cm-2
  • kT=0.91 keV for a model of bremsstrahlung.
  • Comparing this observation with previous drop in flux of about 60%.
  • A disk blackbody model also represents the data well with kT= 0.53 keV
