Microfissures in lamination, cause for concern?

[Apollo1974]

Good day fellow archers,

I went shooting a few weeks ago and notices small fissures in the bottom limb of my Hunter Recurve when I returned. Mind you the temperature outside was -10C (14F) outside, but I imagine the bow can handle the cold. There is no de-lamination of the fiberglass to the wood.

Size of area affected is about 1/2" X 1/2".

Any input would be appreciated, Thank you
Stephen
