Yes they can be predicted. The Aurora Borealis is caused by high-energy particles from magnetic storms on the sun bombarding Earth's atmosphere and those storms can be detected before the storm reaches us.
This is a great website for Aurora Borealis forecasts. They'll even send you emails when displays are expected and where ==>http://www.gi.alaska.edu/predict.php3

Yes they can. You get about 36 hours warning. When there's a solar storm, which is visible in the form of a large number of sunspots, the particles which cause the aurora arrive in the Earth's ionosphere about 36 hours later. It's a matter of practical importance because short-wave radio communications are disrupted. If you want to know more, talk to anybody who has anything to do with short wave radio; Voice of America, BBC World Service or any of the international radio service websites may be able to help. But sunspot activity follows an 11 year cycle. The next year for frequent sunspots and aurorae will be about 2011.

The Aurora Borealis usually happens in the poles, so it happens rarely in countries between the poles. And I don't know if it can be predicted. On my way back home from my catechism, my dad pointed the Aurora Borealis, and that's about the only time I've seen it in the last two years, no matter how late I stay up.

I can be partially predicted by the solar activity. If there is a sudden burst of solar activity the AB will be brighter.

Don't know, I'm too far away from such locales
