Event List


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 (preparing for publication),

and during solar flare rise time,

during solar flare decline time,

during the entire solar flare duration.
