Title: NELIOTA: Results from the 6.5 yr monitoring campaign for lunar impact flashes
Abstract:

We present scientific results from the long-term observations of lunar impact flashes of the ESA-funded NELIOTA program. Using the 1.2 m Kryoneri telescope and the fast frame-rate cameras of the system, NELIOTA has observed over 175 validated lunar impact flashes since the beginning of its operation in early 2017, while other ~100 have been characterized as suspected. We will present results concerning the dimensions, the masses and the appearance frequency of the meteoroids in the vicinity of the Earth. Moreover, statistics for the temperatures of the collisions and the calculation of the meteoroid frequency on various distances from the Earth and the Moon provide quantitative results for the risk assessment for space and satellite missions as well as for future establishment of lunar bases.
