Goose Bay Riometer Observations by Raymond J. Cormier Pdf

At Goose Bay, Labrador, 30-MHz riometers using a four-corner reflector antenna have been in operation since November 1971. An 18-MHz riometer using a zenith-pointing antenna has been operational since June 1972. A quiet day curve of 30 MHz has been constructed for the Goose Bay 30 MHz, and useful hours of operation for an 18-MHz riometer at this particular site are discussed. The usefulness of the four-corner reflector antenna over a single zenith-pointing antenna is discussed, in particular, in an auroral environment. Examples of data illustrating the performance of the antenna system are presented. The data selected are for the geomagnetically active period of mid-April to early May 1973. (Author).

Analysis of Sweep Frequency Oblique Polar Region High Frequency Radio Propagation Measurements by Alfred E. Reilly Pdf

The Chapman-Davies-Littlewood technique for the computation of the equivalent path of an ionospherically propagated High Frequency (HF) radio signal was used to determine the most probable modes of oblique propagation and the corresponding frequency windows that existed during six experimental aircraft flights in the polar region. In comparison to these results, the Elkins-Rush HF Polar Predictive Model has been found to be inadequate for short-term propagation predictions. These oblique propagation measurements have verified Feldstein and Starkov's conclusion that the magnetic Index Q is a good indicator of the position, shape, and size of the Instantaneous Auroral Oval as they have defined it on the basis of ground-based optical measurements which they subjected to statistical analyses. An approach has been developed which sheds new light on the behavior of HF signals propagating via the polar ionosphere. On the basis of the results achieved using this approach, it is recommended that an attempt be made to develop a new method of predicting short-term polar region HF propagation conditions well in advance (that is, an hour or more in advance in real time). A hypothetical example of an application of such a method is given. Action should be taken soon to exploit this possibility. Additional work could extend the applicability of this approach beyond anything that has seemed feasible before. New understanding of the physics of the polar ionosphere could result. It is hoped that this report will stimulate the experimental and theoretical research that will result in this increased understanding of the polar ionosphere. (Author).

Intercorrelated Satellite Observations Related to Solar Events by V. Manno,D.E. Page Pdf

The European Space Research Organisation put its first satellite into orbit in March 1968 and was successful with two more before the end of that year. It was not entirely surprising therefore that the third annual ESLAB/ESRIN Symposium should in some way deal with the results obtained. This book is the Proceedings of that Sym posium which, for reasons which Dr. Trendelenburg explains in the introductory talk, concentrated on intercorrelating phenomena occurring during solar events and in particular during the event of 25 February 1969. It is generally acknowledged that space data could yield a much more fruitful harvest if measurements taken simulta neously in different regions of space could be compared and the detectors inter calibrated. ESRO therefore sought right from the start to encourage this comparison of data. The first two days of the Symposium (16 and 17 September 1969) were devoted to review lectures on inter-related phenomena occurring on the sun, through inter planetary space and the magnetosphere right down to the earth's ionosphere. The last two days were used to hear papers presenting results obtained from the ESRO and certain U. S. S. R. and U. S. A. satellites during the solar events around 25 February 1969. The Proceedings published here follow the same sequence as the Symposium presentations. Because of the short time interval between the solar event and the Symposium, some of the data presented in the second part must be regarded as preliminary.
