  The Soft X-ray Telescope (SXT) on board Yohkoh revealed that the ejection of
X-ray emitting plasmoid is sometimes observed in a solar flare. It was found
that the ejected plasmoid is strongly accelerated during a peak in the hard
X-ray emission of the flare. In this paper we present an examination of the
GOES X 2.3 class flare that occurred at 14.51 UT on 2000 November 24. In the
SXT images we found multiple plasmoid ejections with velocities in the range of
250-1500 km/s, which showed blob-like or loop-like structures. Furthermore, we
also found that each plasmoid ejection is associated with an impulsive burst of
hard X-ray emission. Although some correlation between plasmoid ejection and
hard X-ray emission has been discussed previously, our observation shows
similar behavior for multiple plasmoid ejection such that each plasmoid
ejection occurs during the strong energy release of the solar flare. As a
result of temperature-emission measure analysis of such plasmoids, it was
revealed that the apparent velocities and kinetic energies of the plasmoid
ejections show a correlation with the peak intensities in the hard X-ray
emissions.
