    The discovery was presented today at the European Planetary Science Congress in Potsdam by David Asher of Armagh Observatory in Northern Ireland.
    ...
    "Our results demonstrate some of the routes taken by cometary bodies through interplanetary space that can allow them either to enter or to escape situations where they are in orbit around the planet Jupiter," Asher said.
    ...
    Comet Kushida-Muramatsu has escaped from the giant planet and will avoid the fate of Shoemaker-Levy 9 for the foreseeable future," Asher said.
    ...
    The results of our study suggest that impacts on Jupiter and temporary satellite capture events may happen more frequently than we previously expected," Asher said.

    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.

    The densest part of that trail was probably about 30,000 miles (48,000 kilometers) wide, yet Earth, traveling in its orbit around the sun at 18.5 miles per second (29.8 kilometers per second), swept through it in only about a half an hour. What to expectIn 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. But while another short-lived outburst seems probable this year, it likely will not be of the same intensity as what was seen in 1969.

    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.
    ...
    RS-13/5 ======= Dave, WB6LLO, has operating information for both RS-15 and RS-13 on his personal web site.In addition to satellite data, antenna information and AMSAT-NA Jewelry Contest information is also featured.The WB6LLO web site URL is:

    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.

    "We're not trying to make a precise estimate," Asher said.
