This report describes the auroral-zone scintillation morphology as deduced from two years of observations made at Poker Flat, Alaska, using the DNA Wideband satellite. The data confirm that magnetic activity is the principal factor in determining the level of both nighttime and daytime auroral-zone scintillation. No systematic seasonal variation in activity was found, although the second year (1977-1978) showed a significant increase in overall activity when compared with the first ...
