Kuulkers et al. 2007
(A&A):
- ISGRI spectrum can be described by a powerlaw
with index 2.2.
- The non detection by JEM X, if due to
absorption, implies Nh>1e23 cm-2

Kuulkers et al. 2007
ATel 1005:
- active on Feb 15 2007 between 18:35 and 22:17 UTC
- ~11 mCrab between 20-60 keV, <5 mCrab in 3-10
and 10-25 keV

Kuulkers et al. 2007
ATel 1008:
- Possibility of association of IGR J17453-2853 and
GRS 1741.9-2853
- Spectrum of GRS 1741.9-2853
is consistent with the 20-60 keV flux measured with INTEGRAL.
- Both sources were active at the same time in April 2005.

Muno et al. 2007
ATel 1013:
- Association of IGR J17453-2853 and GRS 1741.9-2853 strengthened
- Chandra spectrum of GRS 1741.9-2853 is powerlaw with Gamma=0.9
- NH=9.0 x 1022 cm-2
- 2-8 keV flux 3e-11 erg cm-2 s-1 <=> for D=8 kpc estimated intrinsic 2-8 keV
luminosity of 4 x 1035 erg s-1.

Porquet et al. 2007
ATel 1058:
- XMM source location compatible with those of CXOGC J174502.3-285450,
AX J1745.0-2855, and GRS 1741.9-2853.
- 2 X-ray bursts observed =>consistent with bursting behaviour of GRS 1741.9-2853
- Outburst duration is at least 7 weeks for this transient.
- Last XMM-Newton observation, April 3-4, 2007, XMM-Newton/EPIC count rate decreased by about factor of 2.5 in
less than one day.
