Which meteor shower produced the highest rate of meteors ever observed?
The Leonid stream
The Leonid stream is much more favorable for producing storms, and generally tends to produce one every 33 years or so, although it has sometimes been disappointing. After feeble displays in 1899 and 1933, The appearance on November 17, 1966, provided the highest known rate of any meteor stream ever recorded.
