摘要: We present an automated approach to active region extraction from full-disc MDI longitudinal magnetograms. This uses a region-growing technique in conjunction with boundary-extraction define number of enclosed contours as belonging separate regions magnetic significance on the solar disc. provides objective definition and areas plage Sun. A parameters relating flare potential each are discussed.
