Context. EIT and Moreton waves came into focus in 1997, when a propagating disturbance on a large area of the solar disc was
discovered. The process generating the EIT and Moreton waves has been frequently discussed.
Aims. On May 2, 1998, a halo CME was observed related to an EIT wave, a Moreton wave, a X1 flare, radio emission sources, and
dimmings. We studied this event to find the relation between all these structures.
