Miscellaneous :

Tomsick et al. 2008 ATel 1649:

Extremely hard Chandra spectrum Γ=-0.9
N_H < 1.55 x10²² cm-2

Rodriguez et al. 2009:

Swift XRT spectrum shows a hard spectrum although Γ not consistent with the Chandra value.
Source is a probable HMXB

Tomsick et al. 2009:

No counterparts in catalogues but a faint Ks source is visible in 2MASS image.
Galactic source is favoured, with a slight preference for an HMXB

Masetti et al. 2010(A&A):

Optical spectroscopy of counterpart
R=19.5, Av ~ 3.1
Balmer emission lines at z=0, intrinsically blue spectrum => XRB
d<19 kpc
Spectral shape ressembles that of reddened LMXBs
Spectrum indicative of accretion disc dominating total optical emission
CV not compatible with large absorption and small disrtance to the source
LMXB
