“…In addition to the clearly decelerating waves, high-cadence EUV observations with EUVI and AIA have also confirmed that there are EUV waves that are propagating at nearly constant speeds in the range of 200 -350 km s -1 (e.g., Ma et al, 2009;Veronig et al, 2010;Kienreich et al, 2011;Liu et al, 2011;Warmuth and Mann, 2011, see left panel in Figure 24 for an example). There have also been reports of events with very erratic kinematics: slow disturbances that become even slower (a few tens of km s -1 ), only to accelerate again (Zhukov et al, 2009, see right panel in Figure 24).…”

“…It has an influence on kinematical studies (e.g., Ma et al, 2009;Hoilijoki et al, 2003), and is particularly important when wave signatures in different spectral ranges are compared (i.e., when trying to determine whether signatures are cospatial). Moreover, propagation heights can help to constrain physical models: while wave/shock models tend to predict dome-shaped fronts with a large extent in height, magnetic reconnection models generate signatures preferentially at lower heights (see Section 6).…”

“…This leads to an ambiguity in determining the exact 3D location of an observed feature, and indeed a structure can appear very different if seen from different viewing angles (cf. Ma et al, 2009;Hoilijoki et al, 2003). Bearing in mind these complications, various attempts have been made to infer the vertical extent of coronal waves.…”

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.

“…Compilation of the kinematics of other events observed by EUVI and AIA showed either waves experiencing significant deceleration in their early stages (e.g., Kozarev et al, 2011;Ma et al, 2011;Muhr et al, 2011;Warmuth and Mann, 2011) or waves with ≈ constant speeds (e.g., Kienreich, Temmer, and Veronig, 2009;Ma et al, 2009;Patsourakos et al, 2009;Patsourakos and Vourlidas, 2009;Temmer et al, 2011;Kienreich et al, 2011;Liu et al, 2010;Warmuth and Mann, 2011). Irrespective of their initial speeds or deceleration profiles, these waves ended up travelling within a rather narrow speed range of 180-380 km s −1 which is consistent with the fast mode speed over the quiet Sun (e.g., Wang, 2000;Wu et al, 2001;Cohen et al, 2009;Schmidt and Ofman, 2010;Downs et al, 2011;Zhao et al, 2011).…”

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.
