Also, the main one seems to be sprouting away from some cumulus cloud near the horizon with a separate one branching away.
There must have been some really strong wind shears up there high in the atmosphere because after about 10 minutes all three formations started to disperse and started to look like three delicate feathers floating across the sky…it was quite spectacular to see :-)
The three images were taken over a period of 10 minutes with a Canon 70D camera and a Sigma 10-20mm set at 14mm, then I used a Tamron 10-17mm wide lens set at 10mm and for the third image a fisheye Tamron 11-16mm lens set at 11mm, the ISO was set at 100 for all three images…. I had to run very quickly to get all the different lenses as the clouds were changing shape very fast!
