Global Ground-Based Electro-Optical and Radar Observations of the 1999 Leonid Shower: First Resultsis has concentrated on the Israel electro-optical wide field cameras and the time interval centered around the peak of the storm. About 2700 meteors have been digitized, with 680 measured for this analysis.

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.作者: CAND 時間: 2025-3-27 12:44 作者: 未成熟 時間: 2025-3-27 17:24
