Abstract : Simultaneous observation of minute-by-minute ionograms and signal amplitude recordings from Explorer 22 (BE-B) have shown a marked coincidence of high scintillation indices and a height spreading of the sporadic E trace. These observations, carried out at Athens (37 degrees 58 minutes N, 23 degrees 43 minutes E) over a period of 18 months lead to the conclusion that the existence of spreading is usually associated with strong scintillation.
