David Brierley, Russell Eberst and Alberto Rango have reported new observations. David's observations seem to have fallen victim to a data reduction error of some sort, so I did not include them in the present analysis. Once the matter has been resolved, I will revisit the analysis, and issue revised elements if the results warrant. USA 193 5.0 2.5 0.0 4.3 v 262 X 271 km 1 29651U 06057A 08037.25940017 .00139910 00000-0 22798-3 0 04 2 29651 58.4888 92.9603 0006606 78.0281 282.1559 16.02707116 02 Arc 2008 Feb 04.28 - 06.28, WRMS residuals = 0.022 deg Definition of 2-line elements format: http://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/SSOP_Help/tle_def.html The new observations enabled starting the arc after the end of the recent geomagnetic disturbance, revealing the expected retreat of the rate of decay to a more normal value. Using the above elements and a 10.7 cm solar flux of 71, Satevo v0.51 estimates decay from orbit on 2008 March 21, in reasonable agreement with earlier estimates. The uncertainty is at least one week.
