We studied three types of faint emission features associated with solar flares -- moving emission fronts, flare halos and Moreton waves. They are all diffuse, rapidly moving phenomena that have classically been studied using solar movies, because their motion renders them more readily apparent to the eye. We searched for an easier and more quantitative method of analyzing these phenomena using still prints. Using the facilities of JPL's Image Processing Laboratory we applied various VICAR algorithms to eight selected events. The techniques employed include contrast enhancement, isointensity contouring, differencing of images, spatial filtering and geometrical registration. We have studied the spatial extent and temporal behavior of the phenomena, the connection between the three different types of phenomena, the possible relation to white-light coronal transients and different physical models for these features.
