According literature a supernumerary rainbow is defined when below the first rainbow more colors are seen beyond the normal colors. As seen on the pictures a "white" band is seen below the violet color which when enlarged consist of faint colors of green and violet. So we see from the outside to the inside red, orange, yellow, green, blue, indigo, violet and then green and violet.
As I was not sure and did ask for a second opinion to Frank Deboosere, our national weatherman and amateur astronomer. And he confirmed the supernumerary band aswell.
