Hi Wolfmoon, and right back at you with the welcome, even though you are my senior.
Your screen name's a cool one. I like it. It reminds me of the one I chose for myself: American Horse. I knew a fellow "boot" in Marine Corps boot camp by the same name, an American Indian. I've always wondered what became of him, so I thought I'd honor him by using his name for my own screen name here. Maybe he'll see it here. Your name seems to have a little of that same abstraction, in its astronomical explanation. Very interesting.
tks and cul.
