Abstract : The effect of F layer irregularities on trans-ionospheric transmissions and fading at HF at equatorial, auroral, and polar latitudes has been documented. Little has been done on morphology and physics of irregularities noted at sub-auroral latitudes, in the vicinity of the plasmapause. The intensities of the irregularities are considerably less than those observed at equatorial and high latitude regions. The scatterers in this region are at times correlated with magnetic activity and at other times present during periods of low magnetic activity, including the recovery phase of magnetic storms.
