Daniel might have been a bit too explicit concerning my talk. The
streams I checked were Draconids, Bielaids and Schwassmann-
Wachmann-3ids. At least in the range of delta a0 I checked I do not
forsee a major storm from these streams. In the case of the SW3-
ids there may be a minor shower this June, and some others in
2011, 2017, and a better one in 2022.

I did not check the Leonids at all (except for some tests of the 1999
and 2001/2002 showers to verify the method). As far as I remember
Rob McNaught's and David Asher's work, the encounters with the
trails in the 2033 periods do not look very promising. One could also
try to extend the computations to 2066 and 2099..., but that had no
top priority for me :-)
As for the SW3ids, Rainer Arlt, Michael Jaeger and myself plan a
paper in an upcoming issue of WGN, dealing with the desintegration
of the comet in 1995 and possible encounters with the 1995 and
other trails in the years to 2030.
