Report time. October 14, 19:00 UTC 1990- 049A (#20638) ROSAT The 2426 kg object was decommissioned on February 12, 1999. My careful analysis with different methods (semi-analytic, Special Perturbation (SP) and Orbit evolution) based on the last seven ELSETs 11286.225... - 11287.278... shows the decay on October 24 +/- 01 days. The SP- programs with different atmospheric models and the forecasted SFX an AP data for the next 12 days show a tendency to the late October 25. The Orbit evolution methods - see Ted Molczans SATEVO data - looks in the direction of October 23. It would be interesting to see the tumbling behaviour of the satellite. Is it magnitude really steady as recent observations possibly have shown or is the amplitude only very small?
