Abstract

A PRELIMINARY study of knee-whistlers observed in the late morning of a quiet day, July 26, 1967, 1206–1236 UT (Kp = 2–), by means of a wide-band (0.5 to 11 kHz) VLF goniometer receiver at Halley Bay (333.4° E of N, 75.52° S, generalized invariant latitude at 100 km: Λ′ = 61.02°) has revealed the existence of marked longitudinal variation (∼3: 1) in electron tube content on an L-shell (L ≃4.7–4.8) just outside the plasmapause.
