47 3.0 Var. The population index, a term computed from each shower's meteor magnitude distribution. Calculated maximum number of meteors a single ideal observer would see per hour, if the radiant is directly overhead and the limiting magnitude is 6.5. Details in the above table correct according to the best information available in June 1998. Maximum dates in parentheses indicate reference dates for the radiant, not true maxima.
Some showers have ZHRs that vary from year to year.
