Coronal “EIT wave” is a large-scale wavelike phenomenon propagating across the major partof the Sun. Debates are being continued regarding a more suitable name for it, its sourcedriver, and its nature. “EIT waves” have been widely explained in terms of fast-modewaves, despite that the model contradicts with many observational features. Two-types ofEUV waves were predicted 10 years ago. With the recent high-cadence observations, mainlyfrom SDO/AIA telescope, more and more evidence has been revealed in favor of the two-wavemodel. In this paper, after summarizing different names used for EIT waves in theliterature, we show how the community are getting close to reaching a consensus on thenature of EIT waves.
