Observations with the Extreme Ultraviolet Imaging Telescope (EIT) on SOHO revealed the existence of transient waves which appear to propagate across the disk from a localized starting point. These EIT waves may be the coronal counterpart of previously discovered Moreton waves. Moreton waves have long been thought to be associated with solar flares, though this may have been because flares are more easily observed than other phenomena, such as Coronal Mass Ejections. EIT waves are observed much more often than Moreton waves, though this may also be due to detection efficiency. In this study, we hope to gain a better understanding of EIT waves, and in particular their initiation, through their relationship to other solar events. This study uses a complete catalog of EIT waves observed from March, 1997 to June, 1998; a period in which 175 waves were found. For each wave, the following ancillary data sets were examined for co-temporal and co-spatial events: GOES X-ray Monitor, LASCO Coronagraph, and Type II radio burst data. EIT waves are classified according to a system which measures the reliability of the existence of the event. We investigate the rate at which each class of EIT wave is associated with flares, CMEs and Type II events. Data are further divided into limb and disk events in order to correct for detection efficiency and biases. An investigation of EUV dimmings is also included as they offer clues to the relationship between EIT waves, flares and CME's.
