The clustering of micrometeoroid impact events on satellite--borne detectors (see e.g. Hoffmann et al., 1975) poses a question whether similar phenomena can be identified as well among larger particles observable as meteors. In fact, there is a strong conviction maintained by many observers that meteors within the streams are observed to be clustered in pairs or larger groups more frequently than one could expect from chance distributions. The rate of the dispersive effects indicates that the lifetime of any group of meteor particles is very limited. If real, the groups must be due to recent fragmentation of larger meteoroids.
