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
