We found the current-carrying regions flare two to three times more often than the regions without large currents. Also, the average flare magnitude is three times greater for the group of active regions with large current systems than for the other group.
We can give a forecast of 'all clear' for a few hours, which is long enough to make an EVA (extravehicular activity).
There are many ideas, and I think that's the problem. We don't really understand how that works.
We have a much better insight into what causes the strongest, most dangerous solar flares, and how to develop forecasts that can predict an 'all clear' for significant space weather, for longer periods.
