Perseid one-revolution outburst in 2004

In 2004 August 11 at about 21h UT, the one-revolution dust trail of the Perseids' parent comet 109P/Swift-Tuttle is calculated to pass within 0.0013 AU of the Earth's orbit and we expect this to cause a moderately strong, short outburst of mainly visually dim meteors. We have drawn conclusions from our prediction model that has been quite successful in predicting recent Leonids storms. We also discuss the possibility of enhanced annual rates because perturbations by Jupiter will now direct all incoming Perseid meteoroids about 0.01 AU closer to the Sun, which allows the possibility of the Earth passing through the densest core of the annual stream.
