“…in agreement with the theoretical picture drawn by Axford et al (1965). A tubular "bundling" of the lines of force drawn back into the tail from each of the magnetic poles would result in a thickening of the sheet toward the flanks also.…”

“…Particle measurements by Anderson (1965a, b), Anderson et al (1965), Freeman (1964), Gringauz et al (1960) , McDiarmid and Burrows (1965), Montgomery et al (1965) and Singer et al (1965) have found enhanced particle fluxes on the night side of the Earth. Certain of these are probably related to the neutral sheet ' (Axford et al , 1965). Particularly pertinent in this respect are measurements by Frank (1965) with the Explorer 14 satellite which revealed the formation Of an ''electron tail" of the magnetosphere.…”

“…This model (Williams and Mead, 1965), employing a current sheet and consequent tail configuration similar to that observed (Ness, 1965) and suggested (Piddington, 1960;Axford et al, 1965;Dessler and Juday, 1965), was quite successful in explaining quiet time electron distributions a s observed at 1100 km and thus demonstrated the strong influence of the geomagnetic tail in determining quiet time trapped particle spatial distributions. In this present study current sheet parameters were held fixed a t an inner edge of 8RE and an outer edge of 200 RE for all available cases.…”

“…Furthermore, recent measurements (Bame et al, 1966) indicate a sheet thickness of -6 RE a t 1 7 RE and an extension of the sheet across the magnetospheric tail. Thus a current system in the tail region having spatial characteristics similar to that discussed by Axford et al, 1965) is indicated. * Nevertheless, in three cases, the A c motion is in good agreement with the predictions of the presently used simplified tail configuration employing simultaneously observed tail field strengths.…”

Using data from the polar orbiting satellite 1963 38C, the behavior of the high‐latitude energetic (≥ 280 kev) electron trapping boundary, Λc, at 1100 km is presented for the period March 15 through June 3, 1964. A sudden collapse of Λc to lower latitudes during the onset of magnetic storms, as indicated by Kp and Dst, is found to be a characteristic feature of the low‐altitude trapped electron population. Details of this behavior are presented and discussed. In addition, during this time period, the NASA IMP 1 satellite sampled field characteristics in the geomagnetic tail. Correlated observations of the simultaneously observed behavior during magnetic disturbances of the 1100‐km trapped electron population and of the field strength in the tail are presented. In three cases there is agreement and in one case disagreement with the latitude decreases that are predicted with an extended geomagnetic tail configuration. These results are considered to be direct evidence of the important influence exerted by the geomagnetic tail field in governing not only the quiet‐time trapped particle distribution, but also the behavior of the trapped particle population during magnetic storms.

“…Numerical simulations are also in vogue at this time. Early studies of the aerodynamic and MHD interactions of the solar wind with the geomagnetic field were presented by Levy et al (1964), Axford et al (1965) and Siscoe (1966). An interesting utilization of those studies was the Avco-Everett Research Laboratories (AERL) 1963 Christmas card portrayal (see Figure 2) since the work had been supported by that private sector firm.…”

Nowadays, the effects of space weather affect in various ways all communication modes, from cable to wireless to space-based systems. Moreover, space weather hazards include malfunction or even permanent damage of power distribution grids and of telecommunication, navigation and surveillance satellites, disturbances of over-the-horizon (OTH) radar, HF, VHF and UHF communications, surveying and navigation systems that use Global Positioning System (GPS) satellites, surveillance (optical and radar), and satellite tracking. Space weather influences on the Earth's weather and climate is still a developing topic. Little is known concerning the biological effects of space weather, especially regarding astronauts.This Institute could not be timelier. Space Weather, which has been defined as "conditions on the sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-and ground-based technological systems and can endanger human life", encompasses a broad range of phenomena impacting both space science and technology. The effects of Space Weather, while present throughout the solar cycle, gain particular prominence around the peak of the 11-year sunspot activity; the maximum of cycle 23 occurred in summer 2000.The fact that this ASI on Space Weather was held in Europe is particularly appropriate. European countries host a considerable repository of knowledge and world-class facilities in this field. Nevertheless, while Space Weather activities in c...
