R. Lunsford and G. Zay observed 15,114 sporadic meteors between 1992
and 1996 and their data are analyzed in this report.
The data reveal a distinct seasonal trend with rates from July through
December being 1.31 ± 0.10 times those from January
through June. After the effect of the changing direction of the apex
of Earth's way is removed, it is found that the July through
December rates are 3 ± 10% higher than those from January through
June. The average corrected hourly rate for sporadic
meteors between 1992 and 1996 is 10.7 ± 1.3 at 2:00 am local
standard time under a limiting magnitude of 6.5, which is
consistent with observations made between 1981 and 1991. Copyright

This is nice example of how good data obtained from amatuer visual meteor
observers can and does get analyzed and published in professional peer
reviewed scientific journals.. Good stuff !!
