INTEGRAL made 3 observations in 2003 April of the black hole candidate H 1743 - 322 during the rising part , and close to the maximum , of an outburst .
H 1743 - 322 was previously observed in outburst in 1977–1978 .
The source is located in a crowded region of the sky ( l = 357 ^ { \circ } , b = -2 ^ { \circ } ) and at least 18 sources are clearly detected in the field of view of the ISGRI gamma-ray imager during a 277 ks exposure .
These are well known persistent X-ray binary sources and 3 transient sources in outburst .
The combined 5–200 keV JEM-X and SPI spectrum of H 1743 - 322 is well fit with an absorbed ( ( 2.5 ^ { +4.3 } _ { -2.5 } ) \times 10 ^ { 22 } atom cm ^ { -2 } ) soft ( photon index 2.70 \pm 0.09 ) power-law model , consistent with H 1743 - 322 being in a high/soft state .
