“…Warmuth et al (2004) found a 100% correlation between type-IIs and Moreton waves. Finally, radioheliographic observations show that the sources of type II burst are generally consistent with coronal wave signatures (e.g., Pohjolainen et al, 2001;Khan and Aurass, 2002;Vršnak et al, 2006).…”

On the Nature and Genesis of EUV Waves: A Synthesis of Observations from SOHO, STEREO, SDO, and Hinode (Invited Review)

A major, albeit serendipitous, discovery of the SOlar and Heliospheric Observatory mission was the observation by the Extreme Ultraviolet Telescope (EIT) of large-scale Extreme Ultraviolet (EUV) intensity fronts propagating over a significant fraction of the Sun's surface. These so-called EIT or EUV waves are associated with eruptive phenomena and have been studied intensely. However, their wave nature has been challenged by non-wave (or pseudo-wave) interpretations and the subject remains under debate. A string of recent solar missions has provided a wealth of detailed EUV observations of these waves bringing us closer to resolving their nature. With this review, we gather the current state-of-art knowledge in the field and synthesize it into a picture of an EUV wave driven by the lateral expansion of the CME. This picture can account for both wave and pseudo-wave interpretations of the observations, thus resolving the controversy over the nature of EUV waves to a large degree but not completely. We close with a discussion of several remaining open questions in the field of EUV waves research.

“…However, the two cases where EIT waves and H Moreton waves have been correlated fall into this category Pohjolainen et al 2001), so here the events with sharp brightenings are singled out for correlation with CMEs, flares, and type II bursts. Table 4 lists the results of this analysis.…”

“…Moreton waves have been modeled by Uchida (1968Uchida ( , 1974 as a fast-mode MHD wave, and additional modeling has shown this description may work equally well or better for EIT waves (Wang 2000;Wu et al 2001). There have been two instances of EIT waves and H Moreton waves observed in coincidence, and in both cases the waves developed cotemporally and cospatially Pohjolainen et al 2001). Since Moreton waves are strongly associated with solar flares, if one can directly relate EIT waves to flares, it may be easier to draw the conclusion that an EIT wave is, or is not, in fact the coronal component of a Moreton wave.…”

In an effort to understand what an '' EIT wave '' is and what its causes are, we have looked for correlations between the initiation of EIT waves and the occurrence of other solar phenomena. An EIT wave is a coronal disturbance, typically appearing as a diffuse brightening propagating across the Sun. A catalog of EIT waves, covering the period from 1997 March through 1998 June, was used in this study. For each EIT wave, the catalog gives the heliographic location and a rating for each wave, where the rating is determined by the reliability of the observations. Since EIT waves are transient, coronal phenomena, we have looked for correlations with other transient, coronal phenomena: X-ray flares, coronal mass ejections (CMEs), and metric type II radio bursts. An unambiguous correlation between EIT waves and CMEs has been found. The correlation of EIT waves with flares is significantly weaker, and EIT waves frequently are not accompanied by radio bursts. To search for trends in the data, proxies for each of these transient phenomena are examined. We also use the accumulated data to show the robustness of the catalog and to reveal biases that must be accounted for in this study.

“…In three disk events, the burst sources were located cospatially with Hα, EIT and SXR wavefronts (Pohjolainen et al, 2001;Khan and Aurass, 2002;Muhr et al, 2010). Figure 14b illustrates the spatial association of the type II burst source with the Moreton wave in the event reported by Khan and Aurass (2002).…”

Large-scale, globally propagating wave-like disturbances have been observed in the solar chromosphere and by inference in the corona since the 1960s. However, detailed analysis of these phenomena has only been conducted since the late 1990s. This was prompted by the availability of high-cadence coronal imaging data from numerous spaced-based instruments, which routinely show spectacular globally propagating bright fronts. Coronal waves, as these perturbations are usually referred to, have now been observed in a wide range of spectral channels, yielding a wealth of information. Many findings have supported the "classical" interpretation of the disturbances: fast-mode MHD waves or shocks that are propagating in the solar corona. However, observations that seemed inconsistent with this picture have stimulated the development of alternative models in which "pseudo waves" are generated by magnetic reconfiguration in the framework of an expanding coronal mass ejection. This has resulted in a vigorous debate on the physical nature of these disturbances. This review focuses on demonstrating how the numerous observational findings of the last one and a half decades can be used to constrain our models of large-scale coronal waves, and how a coherent physical understanding of these disturbances is finally emerging.
