Star trails create arches over the horizon in a long-exposure picture of the night sky taken from Mount Kilimanjaro in Tanzania.

You had me going about the gravity waves Sam.  Then I realised they were atmospheric gravity waves.   ;D  I love the photo of the circumpolar stars but just to show that an amateur can do even better, have a look at THIS PHOTO  (http://www.eagleseye.me.uk/Sky/Wordpress/?cat=17) (top left and 3rd one over) taken by our good friend Dave Eagle.  He's even captured the spectral colours of the stars!   8-)

yes that star trail is cool.

And atmospheric g-waves, they are darn important and *much more interesting*  :devil:

Some nice pictures by Dave Eagle there.

My knowledge of atmospheric g-waves is zero.  I suspect they might be Lizzie's area.   ;D

The word "chromosphere" provided a vital clue.   :laugh:
