Abstract ToO on the new pulsar SXP 175 discovered in SMCAs part of our regular monitoring of the Bar in the Small Magellanic Cloud (SMC) with RXTE we have just detected a new pulsar with a period of 175 s which we have designated as SXP 175. Because of the large field of view (FOV) of the PCA we are unable to locate this object to better than ~1 degree. We there need to take advantage of the unique INTEGRAL science capability to locate this object to a few arcmins, and thereby trigger a Swift or XMM follow-up to locate this object. This technique has proved itself to be hugely successful during our INTEGRAL/SMC observing campaign of 2009 and led to the identification of several new sources - all of which have since been published. The key role that only INTEGRAL can play is to reduce the positional uncertainty down from the unmanageable ~1 degree to the few arcmins which permits identification. Once we have an X-ray position, then we can immediately tap into the wealth of optical & IR data available for SMC systems and greatly enhance the science returns for this new object. We realise now that this INTEGRAL stepping-stone is crucial in maximising our science. Using WebPIMMS and the Integral Observation Time Estimator we predict a 22sigma detection from a 100ks INTEGRAL observation.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
