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.
