I was looking out of the window this evening when I saw these - just had time to run in and get the camera - point and shoot luckily - and snapped both to the left and right sides of the evening Sun. Very pretty - unfortunately they only lasted around two or three minutes before completely disappearing! I couldn't see anything above or below the sun, just these two. They are formed by sunlight being refracted by ice crystals in very high clouds.
