Impatti lunari: frequenze e monitoraggio
  Lunar impacts have been continuously registered by lunar seismographs from 1969 to 1978, and recently they have been also monitored by a NASA project after several observational campaigns steered by IOTA. Video and naked eye observations, with UTC synchronization, can help to identify impact candidates.
