Though it serves no purpose >I find that information being very interesting. Yes, several re-entries have been observed though none (yet), I think, as a result of my decay predictions. As for putting the assumed location of re-entries in my SatEvo decay list, I prefer not. For only a few objects do I hazard a guess as to the possible decay location, and for most of these I report this in a "Decay watch" posting. As I explain in my lists, the "actual" decay times are only my estimates based on the final elsets. Even at best, these times are uncertain by several (15-30 minutes) during which time the object would cover quite a distance along track. To quote a final longitude and latitude would usually be misleading and would be quite impossible for most objects for which even the decay orbits are uncertain. Be thankful for small mercies, however - USSPACECOM are secretive about their analyses of the decay circumstances and only go public with their estimate of the _date_ of decay :( Alan -- Alan Pickup | COSPAR 2707: 55d53m48.7s N 3d11m51.2s W 156m asl Edinburgh | Home: alan@wingar.demon.co.uk +44 (0)131 477 9144 Scotland | SatEvo page: http://www.wingar.demon.co.uk/satevo/
