Abstract
We present here a review of observations and the current theories that attempt to explain coronal EIT waves EIT waves were first observed by SOHOEIT in 1996 Since then careful analysis has shown that they are related to various other phenomena such as CMEs coronal dimming regions Moreton waves and transverse coronal loop oscillations Over the years myriad theories have been proposed to explain EIT waves Early attempts while elegant relied heavily on theories based on precoronal observations More recent work which tends to consider a larger data pool has led to two competing theoretical camps wave vs nonwave models in many cases proposed hypotheses flatly contradict each other Sifting through these seeminglyincongruous models requires a thorough understanding of the available data as some observations make certain theories more difficult to justify However some questions still do not appear resolvable with current data and will likely require help from the next generation of coronal telescopes
