Abstract

We report the detection of unidentified source SWIFT J1656.3-3302, which is located at RA = 254.08, Dec = -33.03 (J2000), galactic coordinates l = 350.60, b = 6.36. The source was detected at 5.7 sigma significance during the Swift/BAT hard X-ray survey (mid Dec. 2004 to mid Sept. 2005). The BAT spectrum (14-200 keV) is very hard with a photon index of 1.26 +/- 0.3. The flux is 1.0E-10 ergs/cm^2/sec.
