... Predicting the 1999 Leonid Storm : David Asher also explained previous Leonid meteor storms (notably the great storms of 1833 and 1966), and together with Rob McNaught (Australian National University, Siding Spring Observatory) made accurate predictions for the times of the `normal' storm trails of the Leonids. The prediction for the 1999 storm (for November 18 02 08 ) turned out to be `spot-on', and made headlines around the world. ...
