I have to assume that the duplication happened during my several attempts to get the readmore tags to work right, which I don't know whether I accomplished or not. Having mistakenly created a new node in so doing makes me want not to try any more. What's more, the actual conjunction is competing for my attention. We in the US weren't on the right side of the earth to see the actual event, but we got the before and after, which is spectacular and much better than fireworks.
