Abstract We report on an RXTE follow-up observation of the ongoing outburst of the newly discovered transient X-ray source MAXI J1543-564 (ATELs #3330 and #3331). At ~2:08 UT on May 10th, 2011, RXTE observed MAXI J1543-564 for about 800 seconds (only PCU2 was active). The 2-60 keV power spectrum of this observation exhibits only a single ~10 sigma quasi-periodic oscillation at a frequency of 1.05+-0.02 Hz. Its FWHM and fractional rms amplitude are 0.5+-0.1 Hz and 22+-1%, respectively.
