Mysterious Untouched Photo -Skywatch Friday

I have posted this one before.  It is one of my all-time favorites.  Do you see the triangle?  And the circle in the middle of it?  Other than leveling the photo for color, I have not altered the cloud in any way. 

I hope you have a wonderful week.  There is lots of interesting weather happening right now. Eyes to the skies!

I have found a meme I love.  Skywatch Friday--if you love clouds as much as I do--join us to see all the amazing things to be found by looking up.
