I hope this means we're in for a lot of nice light shows this winter.

The lightshow last week was the result of a particularly large solar flare. All the solar wind has since passed around/through Earth so it's all over until the next good-sized solar flare, which can happen at anytime; tomorrow, this winter, 2 years from now - it's all happenstance...
Cheers,
