.... aurorae are atmospheric phenomena so strictly I would have thought
within the terms of the ng charter ... BUT, I know that many like to
dash outside when such are seen and try and pick them up, so I suppose
to 'highlight' them in a ng listing, something like " [Aurora] 2013GMT
Cumbria " could be used??? This would be useful as well to highlight
those publishing links to images.

Many thanks to all who did so recently BTW: some stunning photography
there.

Aurora is not weather, mainly taking place above 100 km, but as a
professional weather observer ( Machrihanish 1986-1992 ), I was encouraged
to note all natural phenomena visible in the sky, and had plenty of spare
time, since when aurora were visible, the weather was usually quite good. I
think that it's rather pedantic to argue that we should make the aurora OT,
since quire a few, if not the majority of the participants in this news
group enjoy viewing aurora as much as lightning, snow or any other weather
phenomena.

Should discussions on aurorae in this ng be marked [OT] as they are not
weather related ?

What height do aurorae occur? My understanding is that they are mostly
WITHIN the atmosphere.

Copy extract from this website:
http://earthobservatory.nasa.gov/Study/ISSAurora/

"Most of the light is emitted by oxygen atoms excited from bombardment by
charged solar particles"

So on this basis aurorae are more of a weather (atmospheric) phenomenon
than an astronomical one.

But this is clearly open to much discussion.

I got that book as a present for being a good boy at the
dentist's, and it's still on one of my bookshelves. I
remember using the example in it for starting my first
daily weather log. No, not last week ... something like
1959. (What's the age when your milk teeth start
coming out?)

That sounds good Martin ... it might make sorting the posts more
effective. I freely confess to being a 'dash outside' type when
circumstances allow (-:

About eight, I think.
