The interrelationships among coronal mass ejections, solar flares, and filament eruptions have been a long standing issue in solar physics. In particular, timing and spatial relationships among such eruptive phenomena play a key role in understanding any possible causality among them. Presently, observational ambiguities often result from insufficient temporal and spatial resolution. However, we expect that observational capabilities will continue to improve, and in the near future, produce large volumes of solar data with high time-cadence and spatial resolution. We have developed a method of identifying and extracting coherent structures from multi-dimensional sequences of data. The technique is general and may be applied to sequences of solar images in any frequency (e.g., white light, X-rays, UV), magnetograms, and other astrophysical and laboratory data. The spatio-temporal dynamics revealed using this method can provide a new, improved quantitative understanding of coherent and eruptive phenomena. We report on the result of applying this technique to a sequence of 1-min Hα -images from the Kanzelhöhe Solar Observatory. We chose Hα -data for our initial application because many solar eruptive phenomena have observable signatures in chromospheric dynamics and long periods of Hα -observations are readily available. The data set contains quiescent filaments and a filament eruption accompanied by a two-ribbon flare. The analysis reveals the spatially and temporally correlated phenomena and self-similar structures on the solar disk in extraordinary detail.
