Leonid Dust Trail Theories
At the end of the 19th century, Irish astronomers Johnstone Stoney and A.M.W. Downing showed in principle how to predict meteor storms. Their work and later developments applying similar ideas are reviewed here. The theories essentially involve determining the dynamical behavior of dust trails, which are narrow, dense structures within a broader stream. The formation of dust trails and the main...
متن کاملLeonid meteor stream from Ondřejov radar observations in 1965 – 1967
Results of Ondřejov radar observations of Leonid meteor shower in 1965–1967 are presented. Observations performed during previous returns of Leonid meteor showers indicate that both in 1965 and 1966 the peak activity was observed at almost the same solar longitude near L = 235. ◦17. The activity pattern in 1965 showed two well pronounced peaks separated by 23 hours where the second one seemed t...
متن کاملMeteor trail diffusion: 2. Analytical theory
A meteoroid penetrating the Earth’s atmosphere leaves behind a trail of dense plasma embedded in the lower E/upper D region ionosphere. While radar measurements of meteor trail evolution have been collected and used to infer meteor and atmospheric properties since the 1950s, no accurate quantitative model of trail fields and diffusion exists. This paper describes a 2-D analytical theory of mete...
متن کاملSSC00-IV-3 Leonid Meteor Observer in LEO: A University Microsatellite to Observe a Meteor Shower From Space
This paper presents university-based design and development of a micro-satellite for the observation of a meteor shower from the low Earth orbit. The satellite will be launched as a piggy-back payload of a commercial rocket launcher, a few weeks before the 2001 or 2002 Leonid meteor maximum in which thousands of meteors are scientifically expected. The goal of the mission is to conduct the scie...
متن کاملUsing Artificial Neural Networks for Meteor-Burst Communications Trail Prediction
The use of meteor ionisation trails as ‘cheap satellites’ to reflect radio waves between two points on the earth's surface is an established technique, called Meteor Burst Communications (MBC). For MBC systems to take advantage of the different amplitude and duration patterns of different trail types it is necessary to predict these patterns from features of initial signals reflected from the t...
