Is there a name for this effect and is there any way to prevent this from happening? This photo was taken on a Nikon D60 with a Nikkor 50mm 1.8G lens. 

The setting were f/1.8 1/40 ISO-400

This is not the same as the question `is it normal to get significant lens flare with a 50mm f/1.8 Canon prime lens?` as this question is mainly based on what this effect is called, not whether it is normal or not.
