Video and radar observations of the 2000 Leonids: evidence for a strong flux peak associated with 1932 ejecta?

Video and radar observations of the 2000 Leonid shower are presented. We find strong evidence that the first peak in the shower on 2000 November 17 near 8 UT resulting from 1932 ejecta is much stronger than previously recognized and larger than the broader peak on November 18 resulting from 1866 and 1733 ejecta. In particular, we find a TV‐radar average peak flux value on November 17 at solar longitude 235. ◦ 29 ± 0. ◦ 02 near 0.15 ± 0.02 meteoroid km −2 h −1 (Mv > +6.5), which corresponds to a zenithal hourly rate (ZHR) ∼900 assuming a mass index of 1.7. Similarly, we find the second peak on November 18 to be located at 236.
