Abstract
Multi-filter images from the solar corona are used to obtain temperature maps which are
analyzed using techniques based on proper orthogonal decomposition (POD) in order to extract
dynamical and structural information at various scales. Exploring active regions before and after a
solar flare and comparing them with quiet regions we show that the multiscale behavior presents
distinct statistical properties for each case that can be used to characterize the level of activity in a
region. Information about the nature of heat transport is also be extracted from the analysis.
