The leonids meteor shower was slightly active during 17h-20h on November
18 UT, 1999, in Japan.
The Leonids meteor activity was detected by monitoring forward-scattered
meteor echoes of 50 MHz HAM radio wave (JA9YDB, 53.7500 MHz, 50W, transmitted
by K.Maegawa) at Toyokawa Meteor Observatory, Aichi, Japan.
Corrected maximum hourly rate of echoes reached to over 80 +-9.
