Previous measurements of the aspect sensitivity of radio aurora at VHF have yielded two distinctly different values, namely, 10 dB/deg and 1 to 2 dB/deg. In this paper, a previously discussed event is re-analyzed in greater detail in an attempt to resolve this apparent anomaly. The results of this analysis, which takes account of the effects of a number of measurement errors and uncertainties, lead to the conclusion that the aspect sensitivity of the event could not have been greater than [Formula: see text] in the aspect angle interval of approximately 4.5° to 19.5°. The most likely value is between 1.3 and 1.5 dB/deg. It is suggested that the two observed aspect sensitivity curves correspond to different radio aurora producing mechanisms.
