THE AURORAL OVAL AND THE SCINTILLATION BOUNDARY.
Abstract
The transition or boundary between high- and low-amplitude ionospheric fluctuations has been examined as a function of time. The boundary of the scintillation curtain reaches its lowest latitude (54 degrees geomagnetic north) between 1930 and 2230 local time. The most northerly boundary latitude of approximately 80 degrees Gn occurs during the 1030 to 1330 local standard time period. General agreement is demonstrated between observations of Transit IVA at 54 MHz at a subauroral site, Explorer 22 (S-66) at 40 MHz at three sites, and the main zone of discrete auroral events shown by other workers.
