Scientific paper

Previous studies have shown that the flare activity of active regions is intrinsically linked with the vorticity of subsurface flows on temporal and spatial scales comparable to the size and lifetime of active regions. We begin to address the question whether the measured vorticity of subsurface flows associated with active regions can help to improve flare forecasting. For this purpose, we apply statistical tests based on discriminant analysis to several subsurface flow parameters with the goal to differentiate between flaring and non-flaring active regions.
We will present the latest results. This work is carried out through the National Solar Observatory Research Experiences for Undergraduate (REU) site program, which is co-funded by the Department of Defense in partnership with the National Science Foundation REU Program.
