The short burst of Leonids meteor shower was observed during 01h-03h on
November 18 UT corresponding the solar longitude of 235.5 deg.(eq. 2000.0) ,
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, operated
by K.Maegawa) at Toyokawa Meteor Observatory, Aichi, Japan.
Corrected maximum hourly rate of echoes reached to over 120 +-11
(non-shower:20-25) at 02h-03h UT, and over 250 +-40 at 02h00m-10m UT.

@symbol means corrected hourly rate. Es symbol means interruption by
Sporadic E layer. IF symbol means interference by foreign broadcasting.
up/middle/down : hourly rate of all echoes / hourly rate of long(> 20 sec.)
/ hourly rate of long(> 60 sec.) echoes
