the best place to see auroras is either Canada or northern Alaska and Greenland
In the north and south poles.
Probably - though you're better off going further north - maybe Iceland !
In fact you get best ones in Russia, Canada, Alaska, Greenland, Finland and so on but you only see Aurora Borealis in Northern Hemisphere, in South Hemisphere get Aurora Australis.
Auroras occur in the mesospere.
The Arctic and the Antarctic regions.

Yes, frequently. The display of the aurora borealis isn't connected to the seasons. However, while auroras often OCCUR during the daytime, the faint light is difficult to SEE against the bright background of the sunlit sky. So we more often see auroras at night. And since auroras are usually high-latitude events, and the summer days are quite long at high latitudes, it makes sense that we will more often see auroras in the long winter nights - because the nights are longer!
It's somewhat rare to see that far south, but not impossible. As the sunspot cycle starts to ramp up towards the max in 2012 you can expect a better than normal chance of seeing auroras just about anywhere in PA. Even still, the auroras likely to be seen in PA aren't going to be the impressive displays you can see further north in Canada and Alaska. Probably what you'll see in most cases is a bit of hazy color along the northern horizon, best veiwed in winter, when it won't be mistaken for summer haze.

The aurorae are best visible from the Arctic and Antarctic Circles - and/or locations close to them. It's very rare to see the aurorae near the equator or latitudes as far south(or north) as say, Los Angeles.
Auroras appears in the night sky by atoms and molecules. Auroras is lights in the sky.
