A number of models predict strong peaks in the UT early and late morning hours of November 19. The first maximum is thus in good position for European observers unless they are located geographical longitudes east of roughly 30° and observers in northern Africa. The seond peak will be visible from the entire North America.

The understanding of the dynamics of meteoroid streams requires a gap-less profile of the activity. The International Meteor Organization collects visual meteor observations from all over the world to derive complete activity profiles of meteor showers. In 1998, a total of 70000 Leonids were collected, in 1999 more than 350000! Even if you cannot observe from one of the most favorable locations, your observations will be very useful for the global picture of the Leonid meteor shower. Some essentials of the standard visual observing method are given below. Please follow the hints to log a scientifically useful observation.
Meteor observations are collected world-wide by the IMO and made available for analyses. If you wish to contribute to the global picture of the Leonids, please follow the observing guide and send your results to
