That perfect circle around the Sun is created by special sized ice crystals that refract the suns lights and is 22 degrees away from the Sun.
I kept an eye on the sky all day and saw sundogs and my first circumzenithal arc, I have never seen one before so I was very excited, it only lasted a few minutes then it was gone…but what a thrill it was to see!

These images were taken on the 30th June 2018 with just a Canon G15 point and shoot camera that I always have in my handbag and I used manual focus and the auto settings in the camera.
