Aurora Australis - Looking South from our drive way at  7 Costelloe St Wagin.  Had been out for tea at Katanning and whilst travelling home  this sky was in the rear view of the car all the way home whilst travelling north back to Wagin. When we arrived home I set the camera up on tripod and took ONE image on film.  Never saw the image until years later when I scanned the negative strip containing this image.

Colours in aurora -  There are thousands of individual colours in the aurora, each resulting from a specific electron cloud energy transition of an excited atmospheric atom, molecule or ion returning toward a 'ground' (=lowest) energy state, but three are dominant. Near the lower border a green atomic oxygen emission generally dominates; at an altitude of 250 km a red emission from atomic oxygen dominates; throughout the aurora a violet emission from a molecular nitrogen ion is significant. - Written by Gary Burns.
