Lorentz Shaped Comet Dust Trail Cross Section from New Hybrid Visual and Video Meteor Counting Techn assuming a radial profile for the dust trail that is also a Lorentzian, we make predictions for future encounters. If that assumption is correct, we passed 0.0003 AU deeper into the 1899 trailet than expected during the storm of 1999 and future encounters with the 1866 trailet will be less intense than predicted elsewhere.

Coordinated Observations of Leonids in Israelational means. The elaborate preparations led to an unprecedented success, yielding unique observational results. Some of these are included in these proceedings, but their interpretation and incorporation in a coherent picture of the Leonid meteors is still to come.

Kidnap

Search for Organic Matter in Leonid Meteoroids. It is found that neutral iron lines dominate the spectrum, with no clear sign of the CN band. The meteor plasma contains less than one CN molecule per 3 Fe atoms at the observed altitude of about 100 km.
