Abstract:
An ultrasoft transient X-ray source was discovered
near the Galactic bulge region with the Ginga satellite.
The source position was redetermined using the revised satellite attitude
data, and is in agreement with those of transient sources,
KS 1732-273 and 1RXS J173602.0-272541. The X-ray spectrum was
represented by a multicolor disk model with a temperature at
the inner disk radius of 0.7–0.8 keV. The obtained spectral parameters
are consistent with those of black hole binaries.
