The production of geomagnetic micropulsations by meteors is investigated theoretically, and experimental measurements are reported which attempt to detect the meteor-induced signal. The theoretical treatment is of an ellipsoidal meteor trail having a conductivity which is enhanced over adjacent ionospheric regions and thus disturbs the normal ionospheric currents. The magnetic field perturbation at the surface of the earth is calculated from the altered current density. Amplitudes of magnetic signals as a function of meteor position and orientation relative to both observer and ionospheric current are obtained, and results indicate a maximum signal of several milligamma. Observations are reported which attempt to correlate magnetic variations recorded by induction detectors and photoelectrically observed meteors. No obvious correlation was seen in the record covering 59 sporadic meteors. However, statistical treatment of the data seems to indicate a magnetic signal on the fringe of detectability. (Author).

NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
