First time I've heard of a moonbow, but it makes sense.
Just a rainbow illuminated by the moon instead of the sun. The images are
just like a rainbow - except for the stars in the sky and the light pollution! When seen by eye, the colours aren't really visible because of the low intensity so it just looks like a grey arch. The crock at the end is therefore filled with silver rather than gold.
But you can never reach it.
Showery weather is continuing so there may be more opportunities tonight. Hint, the North Coast always gets more showers when the airstream is unstable north westerly - if they're dying out elsewhere us lot will probably still be getting intermittent soakings, with just occasional clear slots (for the moon to shine through), when the showers have dispersed inland.
