Abstract:
At processing meteor observations the outdated and insufficiently reliable methods are commonly used. In particular, the finding outward-atmospheric meteoroid masses comes from the luminosity without providing any estimates of accuracy for calculations. However, in recent years a variety of new dynamics methods has been developed that quite good describe a motion of meteoroids in atmosphere, as well as changing their parameters. In this article, these methods were used by the author to obtain outward-atmospheric masses of meteoroids from the data of European Fireball Network. It is shown that photometric estimates of European observers are much high than actually possible outward-atmospheric meteroids masses. In addition, the author proposes an approximation of trajectories by elementary functions that allows to simplify and speed up calculations.
