The Large Area Telescope (LAT) on board the Fermi satellite is exploring the gamma-ray sky in the energy range from 20MeV to > 300GeV. Since the start of the science phase of the mission the LAT has detected high-energy gamma rays from the Moon. This emission is produced by interactions of cosmicrays nuclei with the lunar surface and depends on the level of solar activity. Moon was detected by EGRET on CGRO with low statistics, but Fermi is the only gammaray mission capable of detecting the Moon over the full 24th solar cycle. Here we report the detection of gamma-ray emission from the Moon during the first 18 months of observation showing the status of the analysis and interpretation
