The first results from the analyses of over 60 geo-effective active regions (ARs) is shown below.
SHARP data (http://jsoc.stanford.edu/doc/data/hmi/sharp/sharp.htm) with a 12 min time resolution is used to quantify the magnetic properties of the ARs. The SHARP parameters calculated over 4 time periods are used in the analyses. Namely, before the solar flare onset,




during solar flare rise time,



during solar flare decline time,



during the entire solar flare duration





In addition, we present the correlation matrices for the subsets of strong (stronger than -100 nT) and weak GSs (with Dst index from -50 nT to -100 nT):
