Hi Jim, Thanks for the reply.....the camera is still running at present , but I hope to finish this particular period of obs very soon . At that time I'll be able to check the movement more accurately. I have already considered a high inc geo , but I think it was moving too fast for that ( Captured a 4.5 deg inc bird a few weeks ago and that moved more slowly). From your description it sounds very much like a bird in hi orbit....I'll have to start a search ;o)) Thanks again, John ----- Original Message ----- From: "Jim Scotti" <jscotti@pirl.lpl.Arizona.EDU> To: "satcom" <john@satcom.freeserve.co.uk> Cc: <SeeSat-L@satobs.org> Sent: Sunday, December 19, 2004 10:02 PM Subject: Re: NEOS > Hi John, > 20 arcminutes in 2 minutes translates to 10 degrees per hour or 240 > degrees per day - that is exceptionally fast and implies if it were an > NEO, > it would have to be extremely close - possible, but not nearly as likely > as > it being a satellite.
