Lens flare

Lens flare typically manifests in images or views through optical systems as several starbursts, rings, or spheres arrayed in a sequence across the image or view. It is caused by the scattering and internal reflection and refraction of bright light in the optical components of complex lens systems, for example a camera. Typically this will become prominent when pointing a device such as a camera too near a bright source of light. Lens flare patterns will angle across the scene and change location with the camera's movement tracking with the the light position and fading as the camera points away from the bright light until it causes no flare at all.
