You should have seen the walls of my bedroom growing up.
I broke my poor Mothers heart.
I was looking at Starry Night and the placement of the sun
during those displays.
There was definatly a 'Window' of time when the sun hit below a certain point
and the things could not be seen.
As for where they actually are in the atmosphere above us.
I wonder how far down they extend.

Frank,
Given you have a good load of those photographs of the NLC display, would it be possible to draw a graph with time on the x-axis, sun altitude on the y-axis and then plot the NLC intensity, now that would be very useful for predicting times for these NLCs (since you've displayed your unmatched ability at drawing already :lol: ).

Bros and Kylie posters would be enough to break any mother's heart.

Touché mon frère.
Ahh the memories, I can hear my mammy now
when trying get me up and go to Art College...
''When, will you, will you be famous!?''
And me responding,
''I should be so lucky, lucky lucky lucky!''
