Aurora Borealis at high noon! The 'BMW Effect'. This very interesting scattering of colour and patterns of colourful light bands were created when I took this shot through the glass pane of the passenger side window of my son's BMW as we were heading on our way to Turtle Point Cottage at Beaver Lake, near Tamworth, Ontario. So then, let's call it the 'Tonferns Scatter', shall we?
