... of extremely low frequency (10-1500 Hz) magnetospheric chorus to all local times and latitudes is investigated ... substorms, and to evaluate the conditions under which chorus is generated. The analysis carefully separates space and ... magnetometer. A study of spatial dependencies shows that chorus occurs in two magnetic regions: equatorial chorus is located near the equator, and high-latitude chorus is located above 15 degrees. An analysis of chorus in each of the regions illustrates that equatorial chorus is definitely related to substorm, whereas high-latitude ...
