I have taken a picture of it but my camera's field of view wasn't wide enough to catch the halo is all its glory. But here it is for your viewing pleasure.
The halo ring is out at the margins and corners of the picture. There was a smaller ring much closer to the moon. The dark splotches in the lower right corner are the upper branches of a huge oak tree in my yard.
The picture was taken about 9:00 pm CDT using an Olympus SP-320 digital camera with the night scene setting from my driveway in Jackson, Mississippi.
