Canada $5 Moose UV Counterfeiting

I was looking over some of my high denominations and happen to have this handy 20x loop with 2 little led white and 1 led UV light. I know the UV moose on the back of the main moose is a security measure and can se it clearly on many I have. The 2 (top block) I was looking at with the UV light show a blurred version of the moose and UV splatter all over including on the selvedges. Its almost like the northern lights in UV . I have never seen nor heard of any such thing. Unfortunatly the little light isn't enough to take a pic to show it but any opinions would be great.
