There seems to be something wrong with my original computation of
the 1812 trail - now it appears that this one also does not intersect
the earth orbit any more. I also looked at the trails back to about
1770, which also do not intersect the earth's orbit any longer. Marco
is of course right that very minor activity is possible, since dust trail
models cannot really exclude an activity. There may be some very
old material still crossing the earths orbit, and double station orbits
are of course very convincing evidence.
