We have created a composite indicator of the flaring activity for a solar magnetic active region. This automated indicator represents a weighted composite of several quantized measurements which have previously been shown to correlate strongly with flare activity, including primary neutral line length (Falconer: 2001, ApJ. 569, 1016; Cui et al.: 2006, Solar Phys. 237, 45), total flux strength, and effective distance (Guo et al.: 2006, Solar Phys. 237, 25). This weighting depends on analysis of the correlations between these indicators and flare activity of past active regions through the entirety of solar cycle 23, making use of archived magnetogram data from the MDI instrument on the SOHO satellite and X-ray data from the GOES satellites. The automated data analysis programs used to conduct this study makes several improvements on previous methods of determining photospheric attributes, especially primary neutral line length, and will be made available for future active region analysis on the conclusion of this project.
