Book Description
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).
