Suburban oven problem

During our last trip our oven developed a issue.The pilot light will light and so will the burner, but about 1 second after the burner lights there is a little poof sound and a orange flame appears back near the pilot light.The flame is about the size of a candle flame.

The rest of the burner works fine and has a blue flame,the oven seems to work ok.

I an just concerned because I never noticed it before.
Thanks for the help.
