Lunar Cloud Observatory Lunar Cloud Observatory (LCO) was established in 1966, with the intention of observing and recording audible phenomena, which they discovered were being emitted from specific lunar clouds. The first successful tests were carried out in 1971, when the team succeeded in observing and recording audible laser pulses reflected from our moon's clouds, using an eyesix ion laser with a millisecond pulse length (developed in the early stages of the project). Their findings have been documented and released to the public over 40 years later, after much debate.
