Abstract
We interpret the historical activity of comet 55P/Tempel-Tuttle in terms of the observed characteristics of present-day short period comets. In this r espect, it is now realized that such comets are liable to undergo significa nt outburst and mantle loss events at intervals separated by of order a few hundred years. On this basis one might well expect comet 55P/Tempel-Tuttle to have undergone several outbursts since its earliest sighing in 1366. Th e limited absolute magnitude data available for 55P/Tempel-Tuttle is not in consistent with the suggestion that the comet underwent outbursts during it s 1699 and 1865 perihelion returns. If the outbursts of comet 55P/Tempel-Tu ttle are interpreted in terms of mantle loss events then the bright, electr ophonic sound producing fireballs reported during the great Leonid meteor s torm of 1833 may have been due to the Earth sampling mantle material ejecte d during the outburst of 1699.
