The BAT survey source Swift J1453.4-5524 is coincident with IGR J14536-5522. This is a relatively soft BAT source (kT~30-45 keV for a single temperature Bremsstrahlung fit) that appears to be variable. In a pointed Swift XRT observation, we find a moderately bright (3.3e-11 ergs/cm^2 s keV in 0.4-10 keV) x-ray source at RA = 14h53m41.7s, dec=-55d21m42.8s, coincident
with the ROSAT all sky survey source 1RXS J145341.1-552146. The X-ray spectrum is complex, requiring at least two components, such as a hard power law (photon index near 1.0) and a soft blackbody (kT~70 eV) with little absorption, reminiscent of certain magnetic cataclysmic variables. This X-ray source is highly variable, particularly in the soft band.
There is a single bright UVOT source at magnitude 17.59+/-0.02 in the UVW1 filter, at RA=14h53m41.1s, dec=-55d21m46s, which does not appear to be variable.
