Grebenev et al. 2007 ATel 1319:
- detected on Oct. 12 2007, over 7 hours of exposition
- 18-45 keV flux was ~17mCrab on the average,
with a peak of 35mCrab.
- Detected up to 70 keV and spectrum described power law with Gamma=-2.7
- not detected during 2 consequent observations with 3-sigma
upper limits of 8.7 and 6.5 mCrab
- probable SFXT

Grebenev & Sunyaev 2010:
- INTEGRAL detection in two different epochs
- Position compatible with location in Scutum-Centaurus arm => distance of ~6kpc.
- Spectra of both outburst similar well fitted
with bremsstrahlung of temperatures ~40 keV, or power law
with Γ~2.5.
- Addition of a cyclotron line at ~30 keV, necessary but cannot conclude on genuine presence
- Source is a new member of the class of SFXT.

Bodaghee et al. 2012 (ApJ):
- XMM observation => refined position
- Nearest IR, Optical is located outside XMM error box
- Best fit => absorbed cut off powerlaw and iron line with NH=21e22 cm-2; Γ=-0.8, Ecut=3.3 keV
- Pulsation at 997s wi12% pulse fraction
- Sg HMXB, possible intermediate sgHMXB-SFXT

Sguera et al. 2013 (A&A):
- Broad band (0.5-60 keV, INTEGRAL, ASCA, Chandra, Swift) +optical/ NIR follow up + archival NIR study
- 3σ upper limit on 0.5-10 keV (18-60 keV) fluxes = 2.9e-13 erg/s/cm2 (8e-12
erg/cm2/s) during out-of-outburst states
- Duty cycle =1.2% with dynamic ranges > 1380 and > 190 in the 0.5-10 and 18-60 keV
respectively
- Discovery of a single very red object within the intersection of the Swift and XMM
error boxes
- Optical/NIR photometric properties compatible with heavily absorbed blue Supergiant
if at 11 kpc
- Tentative orbital period at 2.13 d
