The following elements reflect the second orbit-circularization manoeuvre, on 2000 Aug 21 at about 09:00 UTC: Lacrosse 4 18.0 4.5 0.0 3.6 v 1 26473U 00047A 00235.45277778 .00001000 00000-0 20115-3 0 06 2 26473 68.0033 27.1494 0005028 162.2813 197.8425 14.61473252 00 They were derived using observations by myself and Paul Gabriel, from 21 to 22 August UTC. My points of this morning are: 26473 00 047A 2701 F 20000822092420380 17 25 0535582-071908 18 S 26473 00 047A 2701 F 20000822092450700 17 25 0559320-011764 18 S I allowed Elcor to update all but the inclination and the rate of decay. Mean residuals are about 1 arc min. Barring any further manoeuvres, this should be reasonably close to the final orbit. Additional observations are required to produce definitive elements. Here is the previous history of Lacrosse 4's orbit, based on observations: 1.
