摘要：

We present the results of our Moon impact flash detection campaigns performed around the maximum activity period of the Perseid meteor shower in 2012 and 2013. Just one flash produced by a Perseid meteoroid was detected in 2012 because of very unfavorable geometric conditions, but 12 flashes were confirmed in 2013. The visual magnitude of the flashes ranged between 6.6 and 9.3. A luminous efficiency of 1.8 x 10(-3) has been estimated for meteoroids from this stream. According to this value, impactor masses would range between 1.9 and 190 g. In addition, we propose a criterion for establishing, from a statistical point of view, the likely origin of impact flashes recorded on the lunar surface.
