Description (Dublin Core)

en-US New characteristics of PiB magnetic pulsations which are associated with the substorm in the local midnight sector are revealed from the recordings of a meridional network of ground stations. PiB's are observed during distortions of the auroral arc which enclose a local region of upward directed field-aligned current. An enhancement at about 0.3–0.4 Hz is shown to be a permanent feature of PiB's. In addition, a secondary amplitude maximum at about 1 Hz sometimes appears in the recordings far from the auroral zone. The generation of PiB pulsations in the Pi1 period range is located at auroral latitudes at a low altitude. Low-altitude electric fields and acceleration of auroral particles, low-altitude resonance cavities, and isotropic propagation of waves is discussed in the interpretation of PiB pulsations.
