Abstract Type : Oral Abstract Category : Sun and the Solar System Abstract : Sunspot groups that contain opposite-polarity umbrae surrounded by a common penumbra are known as delta spots in the modified Mount Wilson classification scheme. These magnetically complex sunspot groups are associated with many major solar flares, so the formation of a delta spot can be a precursor of an active region's potential for major flaring. We have developed an algorithm (SMART Delta Finder; SMART-DF) to automatically detect delta spots from simultaneous continuum intensity and magnetogram observations. This tool can be used to analyse archive data as well as working with near-realtime observations. We have used this tool to analyse the past 15 years of data and investigate the correlation between solar flares and delta spots. In this talk, we present this new software package and results from the statistical study of delta spots and solar flares. |
