Hello; My name is Andy Protigal. I condider myself to be a amateur space and satellite enthusiast. I have followed the US manned programs, to some extent, and have recently developed an interest in astronomy. It is through mediums such as this that I hope to learn more about observing satellites, and about astronomy in general. As an engineer and programmer, I invision myself developing software which may assist in my new found interests. I look forward to contributing to this forum, and in exchanging information with all who participate. Cheers ! Andy
