Goal: to research the meteor flow of Leonides 2010- 2012 with photos of allsky-cameras.

The tasks of the research are the following: 1)study of the theoretical material (observation of the historical information, study of the methods of researches of meteor flows)2)treatment of the photos from allsky-cameras for the purpose of definition (finding) of meteors3)detection of the coordinates of radiant4)comparison of our instrumentations with the historical data and detection of the error of the instrumentation 

The object of the research is the meteor flow of Leonides (photos from allsky-cameras)

CONCLUSIONS:•The investigation showed that the detection of the radiant of one

meteorite flow makes possible sometimes to detect the radiant of the other meteorite flows.

•We got to know the historical and the theoretical information about the meteor flow of Leonides. We managed to detect the radiant of the meteor flow on the grounds of the pictures made by all-sky cameras in New Mexico (USA) and Pingelly (Australia).

•By treatment of the photo data were revealed - bolides, fixed the variability by 4 stars. The weak meteor flow from the Big Dipper was discovered.

•This investigation work is a good additional material by study of the topic

“ The small objects of the solar system”.

InferenceThe investigation showed that the detection of the radiant of

one meteorite flow makes possible sometimes to detect the radiant of the other meteorite flows as well as the detection of the other objects – bolides.

It is possible to register the variability of the separate stars.Follows I plan to process the photo data in 2010-2011 in

order to get more informative numbers of data and more accurate conclusions about the probable drift of the coordinates of the radiant; the change of the number of meteors in hour; and finding of maximums in the flow.
