    Haven't found a good occulation in the 1804-1806 time frame that the story seems to call for. However while looking, came upon another interesting event. On 3 Jan 1818 at 21:50:57, it looks like Venus transited Jupiter, a truly once in several lifetimes occurance. From Christmas Island in the Indian Ocean, Xephem says:

    Lat 10 deg 20 min South
    Long 105 deg 41 min East
