Can anyone please ID this satellite?
Hi all
This morning (29-11) Heaven's Above predicted that ISS was going to pass over my house at approx. 6:44 (that's 5:44 GMT). Since we had a clear sky I went out and almost immediately spotted it in the western sky. Or so I thought. Because the longer I looked the more I started to doubt whether it was ISS. Althought very bright, it just wasn't enough. What *really* got me thinking was the fact that it passed overhead north of the zenith, which ISS never does at my location (Rotterdam, Netherlands, 51.9170°N, 4.4830°E). I saw the object move from south west to north east. In the eastern direction it's brightness decreased suddenly very quickly, becoming almost impossible to see, but still a very small dot (moving into earth's shadow I presume). Then I turned around, and ...... saw ISS coming right at me, unmistakably, as bright as the sun, following a path from a more north western to south eastern direction. Can anyone satisfy my curiosity and tell me what object I saw? It looked far too bright for just any satellite. Thanks, Margreet Mol |

Thank you very much! Those pass details match perfectly! The details say
this satellite was deployed from the Space Shuttle, so it's probably not the smallest satellite around. I guess that might explain the unusual brightness. When it passes again tomorrow morning, I'll be looking :-) Margreet Mol wrote in message ps.com... M.H.

Hi Margreet,
Observing from Leiden, I had exactly the same experience with UARS and ISS as you this morning! I too initially mistook UARS for ISS. See my message at the SeeSat mailing list: http://www.satobs.org/seesat/Nov-2006/0283.html I was photographing at that time, so I shot pictures of both UARS and ISS. URL's to those pics are in the Seesat message on the URL above. Cheers, - Marco :-) (with thanks to Ted Molczan for pointing me to your message: I normally don't read this newsgroup) M.H.

Hi Marco
Thank you for your reply. For a few months now I've been lurking in the Seesat-D mailing list, so I read your email in the latest digest yesterday when I got home. It was very amusing to read we had such a similar experience :-) Greetings, Margreet Mol "SatTrackCam" wrote in message oups.com...
