G'day, on December 4th 2013, my friend Barry Littleton brought to my attention a Comet called "Siding Spring" which I think some of you maybe interested in. Below is a couple of links about the Comet which Barry sent me and a pod-cast episode from "The Unexplained with Howard Hughes" where Richard C Hoagland mentions the Comet Siding Spring, Ison and more, which I recently heard.
