The X1.2 flare occurred on 23 April 1998 approximately 
behind the
eastern solar limb. Its C2.0 precursor is identified as a rapidly
expanding system of magnetic loops that was well-observed by Yohkoh. Basic
parameters of this ejection are estimated based on images from the SXT
telescope. The evolution of the X-ray ejection is compared to a sequence
of CME images obtained by the LASCO coronagraph onboard SOHO. Evidence
that the X-ray ejection is responsible for an additional acceleration of the
CME is presented. A possible scenario of the event is suggested.
