The Soft X-ray Telescope (SXT) on board Yohkoh revealed that the ejection ofX-ray emitting plasmoid is sometimes observed in a solar flare. It was foundthat the ejected plasmoid is strongly accelerated during a peak in the hardX-ray emission of the flare. In this paper we present an examination of theGOES X 2.3 class flare that occurred at 14.51 UT on 2000 November 24. In theSXT images we found multiple plasmoid ejections with velocities in the range of250-1500 km/s, which showed blob-like or loop-like structures. Furthermore, wealso found that each plasmoid ejection is associated with an impulsive burst ofhard X-ray emission. Although some correlation between plasmoid ejection andhard X-ray emission has been discussed previously, our observation showssimilar behavior for multiple plasmoid ejection such that each plasmoidejection occurs during the strong energy release of the solar flare. As aresult of temperature-emission measure analysis of such plasmoids, it wasrevealed that the apparent velocities and kinetic energies of the plasmoidejections show a correlation with the peak intensities in the hard X-rayemissions.
