Book Description
Geomagnetic micropulsations in the period range of 0.3 to 120 seconds have been recorded on flux-rate variographs at many widespread locations: Palomar, California, since July 1955; Resolute Bay, Canada, since November 1957; Uppsala, Sweden, since July 1958; Reykjavik Iceland since June 1958; and Huancayo, Peru, since October 1958. The flux-rate variographs consist of pickup coils having a turns-area of 750 x 28,000 cm squared connected directly to galvanometers recording photographically with standard seismograph recording drums.

Book Description
The subject of geomagnetic micropulsations has developed extremely rapidly and it is difficult to know when is an appropriate time to pause and assess the sum total of our knowledge-both observational and theoretical. There has in recent years been a tremendous increase in both the quantity and quality of data and also many theoretical ad vances in our understanding of the phenomenon. Undoubtedly there will be further progress in both areas but it seems worthwhile now to review both our knowledge and our ignorance. This book was essen tially completed by the end of April 1969 and tries to give a summary of the subject up to that time. The Earth is enclosed in the magnetosphere, a hollow carved out of the solar wind by the Earth's magnetic field. Above the ionosphere there is a very tenuous thermal plasma of partially ionized hydrogen in diffusive equilibrium with magnetic and gravitational forces, and ener getic protons and electrons that constitute the trapped Van Allen ra diation belts. Throughout this anisotropic and inhomogeneous plasma, natural and man-made electromagnetic energy propagates in a wide variety of modes and frequency bands. This book is concerned with that class of natural signals called geomagnetic micropulsations-short period (usually of the order of seconds or minutes) fluctuations of the Earth's magnetic field.

Book Description
The plan to hold a conference on cosmic plasma physics originated in the Plasma Physics Division of the European Physical Society, whose chairman, B. Lehnert, took the first steps towards its realization. - ESRIN readily adopted this idea, and preliminary contacts with a number of other groups showed that there was a good deal of interest in bringing to gether people working in different areas of the field of cosmic plasma physics. It was clearly felt that an exchange of views and experience, and an attempt to define problem areas, would be profitable. In this spirit a programme was de vised which covered a large variety of topics, ranging from ionospheric to galactic structures. A diversified programme of this kind runs the risk that the communication between the various fields of specialization remains insufficient. It was gratifying to find that within the wide field of cosmic plasma physics a lively dialogue was in fact possible. The Conference was sponsored by the European Physical Society. Financial support was provided by ESRO. It is a pleasure to acknowledge the excellent suggestions of the programme committee members L. Biermann, N. D'Angelo, R. Gendrin, and B. Lehnert. I should like to thank my colleagues B. Bertotti, K. Lackner, and J.F. McKenzie, and numerous other ESRIN staff members, for their valuable help. I feel particularly indebted to the conference secretary, Miss Sachs, who did the real work while I just signed the letters.
