A COMBINED REPORT ON GENERAL WORKS AND PRELIMINARY STUDIES ON SOLAR RADIO EMISSION AND SOLAR-TERRESTRIAL RELATIONSHIPS THROUGH V. L. F. PROPAGATION IN THE IONOSPHERE

摘要

This is the first annual report on two separate grants, Solar Microwave Radio Emission and VLF Atmospheric Studies, Status and descriptions of the projects, of the Umuarama Radio Observatory, and of the data acquisition system are included. Solar observations on 300 MHz, geomagnetic and geoelectric program as well as plans for measurements at Bage, Brazil during the November 1966 Solar Eclipse are given, Notes and graphs on Residual elevation angle vs. altitude, Monthly mean solar elevation angles and azimuths. Displacement of longitude for a considered sunrise time at several altitudes, along different latitudes are included. Following are also part of the report:n1) Electromagnetic Meaning of Flux Density Measured by Radio Telescope Antennasn2) Results obtained with VLF Atmospherics Measurementsn3) Installation of the Geomagnetic Data Monitoring Station. Diagrams, Graphs and Tables illustrate the data collected thus fax in the first year of this five-year project.
