...Similar radio waves are also observed by artificial satellites outside the Earth (auroral kilometer waves, saucer waves, etc.), and when we look at the Earth from the outside, we can see that it emits radio waves like a radio star in conjunction with auroral activity. In response to the blinking of patch-type auroras, radio waves similar to the chirping of small birds, called the auroral chorus, can be received. In addition, vibrations of the Earth's magnetic field (geomagnetic pulsations) occur along with the blinking of patch-type auroras. ... *Some of the terminology that refers to "Aurora Chorus" is listed below.

…同種の電波は地球外の人工衛星でも観測され(オーロラ・キロメートル波,ソーサー波など),外から地球を見るとオーロラ活動に伴って電波星のように電波を放出していることがわかる。パッチ型オーロラの点滅に対してはオーロラ・コーラスと呼ばれる小鳥のさえずりに似た電波が受信されることがある。またパッチ型オーロラの点滅とともに,地球磁場の振動(地磁気脈動)が起こる。… ※「オーロラ・コーラス」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
