The 1991 Perseid meteor shower was notable for an outburst of activity, particularly around August 12th, which was linked to the return of Comet Swift-Tuttle. While the shower's peak activity is typically around August 12-13, the 1991 shower saw a higher than usual rate of meteors, with some observations suggesting rates exceeding 300 meteors per hour according to Harvard University.
