Abstract

We carried out a wide-field TV observation of the Leonid meteor shower at the Nobeyama Radio Observatory, from 12^h30_m UT through 20^h15^m UT on 1999 November 18. We detected 428 Leonid meteors, along with 55 sporadic meteors. A gentle peak of the activity was recognized at around 17^h UT, when the peak influx rate of meteoroids was 1.1 × 10^-6 km^-2 s^-1 (mag < +5). This secondary peak was at least by one order smaller than the main peak of the Leonid storm observed at 02^h UT over Europe.
