    But the most likely explanation, according to meteor expert David Asher, is that sky watchers this year are seeing an unusually bright version of the annual Taurid meteor shower.Asher, a scientist at the Armagh Observatory in Northern Ireland, explains on the NASA site that Earth is being bombarded by a river of space dust associated with a passing comet.

    Our planet sails through this dust every year in late October and early November.Larger particles in the dust create a meteor shower called the Taurids, so named because the streaks appear to come from the constellation Taurus.

    Normally the shower is too weak and slow to draw much attention.But occasionally the Taurids put on a flashier show.

    In 1993 Asher and colleague Victor Clube published a paper describing why the shower might be more intense in certain years.

    Asher and McNaught were the first astronomers to even attempt to predict the number of meteors a shower would produce.
    ...
    Robert McNaught and David Asher are predicting at 9:56p.m. on Nov. 18, that Earth will pass through the 7-Rev trail and it will produce a storm of 1000 meteors an hour for approximately 130 minutes.
    ...
    McNaught and Asher go on to say that since the 4-Rev trail has had no close encounter with the Earth since it formed it should be intact and very dense.

    This year, however, according to calculations by Armagh Observatory astronomer Dr David Asher, the Leonid meteor shower will be exceptional in having several storm-level peaks on Sunday, 18th November superposed on the normal background level of activity.

    VHF/UHF/SHF ----------- Leonids ======= November's Leonid meteor shower will produce good displays this year and next and strong storms of meteors in 2001 and 2002, that's according to new research by Dr. David Asher, of Armagh Observatory and Dr. Rob McNaught of the Australian National University.

    In 1999, astronomers Robert McNaught and David Asher published a report concerning Leonid dust trails and cited the case of the 1969 outburst.
    ...
    Other reputable meteor forecasters such as Thomas Van Flandern of the United States, Esko Lyytinen of Finland and Jeremie Vaubaillon of France confirmed in their own Leonid studies (to within minutes of McNaught and Asher's) that Earth would indeed encounter the 1932 dust trail again in 2006.

    proposed by professional meteor astronomer David Asher at Armagh. Previous 'swarm' return-years predicted by him have produced more bright Taurids than normal, including some notable fireballs (in 1995, lasting roughly from late October to mid November), and ZHRs of 8-10 (similar to what is seen during their typical November maximum spell) around 1998 October 27-31.David has suggested 2005 could see another autumnal Taurid 'swarm' return.

    According to Armagh Observatory astronomer, David Asher, and co-workers, there will be two additional peaks of activity after the broad stream peak.
