    Spatial and Temporal Identification of EUV Flares in Solar Active Regions
    (2022-12-15) Mahaffey, Theo M
    An automatic method developed to perform flare-finding on Level 1 EUV data from SDO/AIA is described in detail. The data are spatially binned, preprocessed, and compared against a Gaussian white noise background. The methods of Berghmans and Clette (1998) provide the basis for the automated detection algorithm; pertinent adjustments were made to address the high spatial resolution provided by AIA. Preliminary results for a short observation of NOAA active region 12712 from 16:00-16:45 UTC on 2018/05/29 are presented. Future work may include investigation of the link between EUV active regions and periodicities found in various observables, including radio emissions and magnetic field. Accurate determination of the flare frequency distribution for small flares is also a promising application of this method.
