Auroral Acoustics

Researchers investigating auroral phenomena were surprised to hear a “clapping” sound on their recording, which they estimate to have originated during the auroral storm at about 70 meters above the ground. There are stories of the sounds made by the aurora, but it has never before been recorded, if this is indeed real.
