A weather report in the weekend paper informed me that many millions of tons of sand were on the way north from the Sahara. Winds were blowing the sand into the air and it was being carried along at a height of between 5 kms and 7kms above the ground.
It was likely that Sunday's sunset would be memorable.
Five minutes after I'd taken the above photo the sky was a fiery orange. I was in a car and was unable to take a second photo.
With a computer tool I've coloured the photo and created an image that reminds me of how dramatic it was.
