I derived the following elements using observations by myself and Paul Gabriel,
from 21 to 26 August UTC:

Lacrosse 4      18.0  4.5  0.0  3.6 v
1 26473U 00047A   00239.42216435  .00000648  00000-0  13031-3 0    06
2 26473  67.9970  16.7963 0002522 208.8579 151.2490 14.61476889    00

Mean residuals are less than 1 arc min.

There is some indication that a very small orbit-raising manoeuvre was made
during the past couple of days, which appears as decrease in motion and a
negative rate of decay, in this elset based on observations from 24 to 26
August UTC:

1 26473U 00047A   00239.42216435 -.00000284  00000-0 -57132-4 0    05
2 26473  67.9981  16.7972 0002494 216.9196 143.1811 14.61475025    03

It may simply be that we cannot determine the rate of decay accurately over
such a small data arc.

I made the following observation this morning:

26473 00 047A   2701 P 20000826084303370 17 25 0711498+262462 18 S
