摘要：

We compare the coronal transient wave phenomenon discovered by SOHO extreme ultraviolet observations ("'EIT waves") wi-th the associated radio signature of a coronal shock wave (type II burst). 90% of the type II bursts are associated with an EIT wave. On average, the speed derived from the radio burst is about three times larger than the EIT wave speed. Within the sample, there is no correlation between the speeds of both tracers of a coronal disturbance, Under very general assumptions we conclude that both wave phenomena can be different signatures of the same fast magnetosonic disturbance.
