Abstract 4U 1543-624 is an X-ray binary, likely harboring a neutron star, in an18-minute binary orbit. Though it is a persistent source, theSwift/BAT now shows a clear rising flux trend in 15-40 keV; the source has never shown behavior like this in the past. This differs somewhat from other persistent sources, such as Z and Atoll sources, that vary in quasi-regular patterns. It also differs from the behavior observed in true transient sources with short periods, such as SAX J1808.4-3658. The outburst behavior may represent a change in the corona of this source, and a study of coronal evolution in an UCXB is relatively unexplored territory.

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.
