This is the 15-40 keV IBIS/ISGRI field of view near the Galactic Center during a 5x5 dither
Target of Opportunity observation (proprietary data, PI: A.N. Parmar)
of H1743-322 (IGR J17464-3213 = XTE J1746-322)
which was first reported to be in outburst on March 21
(Atel #132;
see also ATEL's
#133,
#136,
#137,
#138,
#139,
#142
and
GCN Circular #2039).
The ToO consisted of 3 observations of 75-100 ksec on 3 occasions in April 2003.
In the 1st observation the `persistent' targets are indicated in white text. Note that
OAO 1657-415 was in or near eclipse in the 1st and 3rd observation. During
(part of) the observations two other transients were seen to be active.
One is a new transient detected by RXTE, XTE J1730-318 (see IAUC's
#113,
#114,
#117,
#153) and a
new transient detected by INTEGRAL, IGR J17091-3624
(see ATEL's
#149,
#150,
#152).
The 3 transient sources are indicated in red in the 3rd observation.
