TV observations of the Perseid meteor shower in 2012–2013

• This paper reviews the results of the meteor observations in Moscow region in 2012-2013.
• Main parameters of the Perseids (radiants, geocentric velocities and orbit parameters) is presented.
• The dependence of the beginning and ending heights by absolute magnitude is analyzed.
• The paper contains results of the Perseid activity analysis in 2012-2013.

The results of television meteor observations during the Perseid meteor shower activity in 2012–2013 are presented. The observations were carried out in the Moscow region using the television system PatrolCa – the patrol camera with the field of view of 56°×44° and limiting magnitude (for meteors) of +4m. The distribution of the Index of Meteors Activity of the Perseid meteor shower in 2012–2013 was estimated. The maximum activity occurs on August 12 with the Index of Meteors Activity (IMA) (λ=140.4°) 192 (±0.03)*103 particles to the Earth per 1 h in 2012 and 122 (±0.06)*103 particles to the Earth per 1 h in 2013 (λ=140.2°). In total for 91 meteoroids radiants, geocentric velocities and orbit parameters were calculated. The daily drift of Perseid radiant was determined. The dependence of the beginning and ending heights by absolute magnitude is presented.
