2004 Oct.29 : Some data were corrected.
I calculated the dust trail which will return in 2004, from Comet 55P/Tempel-Tuttle. Although Leonids appeared actively from 1998 to 2002, a high-scale shower is not expected this year from my result.
However, a small shower may be seen from some trails. The distribution of the dust trais are shown in Fig.1 and Fig.2.
Fig.1 Position of tha new trails. (1932 and 1965)
Fig.2 Position of tha main trails.
All trails : Ejected from 1699 to 1899.
Old trails : Within 0.003 [AU], ejected from 901 to 1666.
From these, the trails which approaches the earth within 0.003[AU] this year were summarized in Table 1. (Detailed data table is hear.)
