Here is an accurate SGP4 elset for the epoch of the ascending node prior to Russell Eberst's last reported observation, on 1997 Mar 24 UTC: Observation arc 1997 Mar 02.18 - 24.89 UTC: Lacrosse 1 18.0 4.5 0.0 3.6 v 1 19671U 88106B 97 83.86856127 .00000030 00000-0 48440-5 0 08 2 19671 56.9772 60.2687 0010104 115.1979 245.0091 14.70734531 06 WRMS residuals = 0.014 deg Lacrosse failed to appear when Russell tried to observe it two nights later, as he reported here: http://satobs.org/seesat/Mar-1997/0219.html It was never seen again, so it is reasonable to conclude hat it was de-orbited sometime between Mar 24.89 - 26.85 UTC.
