Aurora question
 

Having just enjoyed the aurora here in central Scotland I have a question.
Does the phenomena always occur at night for some reason or does it occur
and go unnoticed during the day too?

To answer your question Bob I'm pasting a post from "snock" on TWO :




"technically local midnight brings the most intense part of the aurora over
your location (particles streaming in from the sun will logically gather on
the 'lee' side of the Earth from the sun, i.e. midnight) but really it has
more to do with the current activity than the time of day, midwinter in
Alaska brings 'daytime' auroras but of course it is dark

Thanks for that. I've also noticed it happens mostly when it's icy cold too.

It's probably due to the clear visibilty we get during a polar maritime Bob.
Nothing like fresh air really, it's a pity we experience so infrequently.
However with the current decrease in "Global dimming" who knows, the only
barrier then would be urban light pollution. Oh and not to mention the
Methane HydroCarbons released when the Earth is 10C warmer ;)

Does a falling tree make a sound, when no one is around ?

If a man says something when his wife is not around, is he still wrong?
