An analysis of Rossi X-ray Timing Explorer pointed observations of the black hole transient 4U 1543-475 (see ATEL#98 and IAUC#7920) indicates that the source is currently in transition, possibly to the low hard state. The X-ray spectra of two observations taken on July 23 and July 24 show a multicolor disk component with ~0.4 keV inner disk temperature and a power law with a photon index of ~2.65.
