The track fits, though. > There is no way you could have a S-N satellite entering shadow this time of the year. You would have Resurs 1-4 Rk 98-43 G 4 degrees above, trailing by 24 s. or close to 10 degrees. Culmination ranges are 933/936 km, so speeds are close. But Resurs is predicted brighter than ERS (3,4/5.6) Could your time be wrong ?? Björn
