Io-D arc on 130106 at Paris Observatory Nancay Station

Io-C and Io-D are radiated from the Jovian southern magnetic hemisphere and are generally left hand polarized.

Io-D is observed infrequently, it rarely reaches 20 MHz. Many of the modulations seen on the band of Io-D radiation are caused by the solar wind.

For a method to use Jim Sky's wonderful Radio-Jupiter Pro 3 software to predict Io-D events see:
