Luxembourg effect on 24 MHz in connection with strong aurora
Abstract
During a wave propagation experiment on 24 MHz in northern Sweden an unexpected phenomenon was found. This was somewhat similar to the previously known Luxembourg effect with the exception that this high frequency was used but with much lower transmitter power, 600-800 W, in comparison with the ordinary observations of the Luxembourg effect. The phenomenon was seen as sudden increases in signal strength and simultaneous transference of modulation from one frequency to another, 1.5 MHz higher. The available recording is given but the existing situation at the time of observation is also demonstrated by means of other ground-based instrument recordings.
