标题：Magnetic Field Observations with Soundign Rockets (b. Electric Fields and Current System) (Proceedings of the First Symposium on Coordinated Observations of the Ionosphere and the Magnetosphere in the Polar Regions (Part I))
摘要：Detailed observations of geomagnetic field variation in and near the aurora were provided by the new three-axis flux-gate magnetometer experiments acquired with two sounding rockets (S-210JA-24 and 25) that were launched on August 17 and September 1, 1976 at Syowa Station, Antarctica. The magnetometers were sampled at a rate of 5 samples per axis per second. The magnetic differences were obtained by subtracting the extrapolated values of the IGRF 1975.0 from the measured values. The experiment with the JA-24 rocket exhibited a pronounced increase in magnitude with the increase in height from 110 km to the apogee of the vehicle (118 km). The result of the analysis of rocket attitudes with the geomagnetic aspect sensor are also discussed.
