'X-FLARE: Sunspot 930 has just unleashed another big solar flare, an X3-class explosion at 0240 UT on Dec. 13th (9:40 pm EST on Dec. 12th).'
As I mentioned in another thread there was a major solar flare reported today (at around lunch time, wednesday 13th, for eastern oz) from the large sunspot present atm.
Given it takes between 12-24 hrs front leading edge of plasma cloud to hit earth, and activity can last for as much as 48 hours - altho that is unsual, more like a few hours to 24 hours in duration max.
Tonight and tomorrow night for southern latitudes ie below a line from Perth to Sydney, could see some activity, specially at dark sky sites, in the southern skies
of course Tassie is always in the box seat for such events, if clouds and bushfires arent a probem!
But then it is Dec and the chances of the IMF rolling over and going south easy arent as great as during spring and autumn, but if the plasma cloud has the right magnetic component/orientation (south) then it could get interesting!
good luck!
