Leonid dust trail positions in 1866

The Leonid storm of 1866 occurred when the Earth passed through the dense Leonid dust trail that had been generated around the 1733 return of Comet 55P/Tempel-Tuttle. The timing, Nov 14.05 UT, shows that the meteor storm was observable from Europe. A fuller explanation of these trail cross section plots is available. Go to Armagh Observatory Leonid page.
