| Description | The most frequent and intense waves observed in the geomagnetic tail region are short wavelength electrostatic broadband emissions. Early observations of these waves were made by using IMP 7 and 8 respectively. A broad frequency range for the waves was found, from about 10Hz to several kHz, with an average r.m.s. electric field amplitude of about 1mV/m was found. Other less frequent and less intense wave modes were also identified: magnetic noise bursts and electrostatic electron-cyclotron waves. The highest frequency of occurrence of the electrostatic noise as found in the region near the plasma sheet boundary when anisotropic fluxes of ions streaming either earthward or antiearthward were present. It was confirmed, by using ISEE data that the waves were usually observed during times of ion streaming and that the intensity and frequency range was maximum in the plasma sheet boundary layer and fell off dramatically in the tail lobe and central plasma sheet regions. It is suggested that increases in the electron and ion temperature in going from the tail lobe to the central plasma sheet are a result of scattering of resonant, boundary layer plasma. |
