Abstract: | Massive television observations of meteors aimed at verifying the existing and finding new meteor streams create the task
of the reliable preliminary determination of the detected meteor membership in a particular known stream. The mostly widely
used method of meteor identification is connected with the estimation of the distance between the great circle of the meteor
and the point of the examined radiant. Often observers perform this estimation without checking the possibility that the same
meteor belongs to another stream. When several streams occur simultaneously, many meteors can be members of two or more streams.
When the determination of the meteor membership is done in a subjective way, it may lead to an overestimation of strong streams’
and an underestimation of weak streams’ activity. In this work, we describe a method and algorithm for the determination of
the meteor membership in known streams which were tested using real television observations and were successfully used at
INASAN. This algorithm is almost completely automatic and allows for the obtainment of additional information regarding meteor
streams. We also show some results of the processing of 2254 meteors observations obtained with the FAVOR camera from July
31, 2006 to October 21, 2006 using the proposed method. The work is part of the program for the creation of the Verified Catalogue
of Meteor Streams. |
