"....For the first time researchers accurately predicted-to within minutes-
when the two-day-long storm would peak.....
Yet David Asher, of Armagh Observatory in Northern Ireland, and Rob
McNaught, of the Australian National University in Canberra, nailed this
year's Leonids peak almost exactly...
Asher and McNaught credit several Russian researchers, including E.
D. Kondrat'eva and R. A. Reznikov, who pioneered this method of meteor
forecasting in the mid-1980s but went largely unnoticed by Western scientists,........etc.
..while Asher and McNaught are calling for intense storms with ZHRs
of 15,00 or more[in 2001 and 2002]."
I have edited down the note considerably so you may try the web sight or your local library to see the details.
