Space Weather Forecasting: Quiet Times Ahead

SOHO/MDI magnetograms combined with the Potential-Field Source-Surface (PFSS) model can be used to generate a model of magnetic field lines in the lower part of the solar corona. When these models are compared to the loops visible in TRACE imagery, a good match (as in this case) indicates that the region will not generate flare events over the next few days.
