It's a Sun Dog, with so many people watching the skies that never even bothered to look up before its no wonder there are so many vids and pics denoting them as second suns. More properly called “parhelia”, these can look very striking indeed, and occasionally can be so bright it looks like there are three Suns in the sky, basically all these effects are caused by sunlight streaming through – and being refracted by – ice crystals in the air. Imagine the air above and around you full of teeny tiny prisms, and you get the idea.
