	Whatever elsets you have now should be close enough.  The shuttle
is bright enough (i.e. easy to spot) so that having predictions that are
some seconds off won't matter too much.  I have used days old elsets
before to predict the reentry pass so I could observe the plasma trail.
These passes happen about 10 minutes before the landing in Florida.  I
just start observing a few minutes before the predicted time.  So I
figure that if elsets are good enough for within 10 min of landing they
should be good enough for the last few orbits.
