The radio beacon signals on 40 MHz, and 140 MHz and 360 MHz from ATS‐6 satellite at 34°E longitude, received at Ootacamund, India (11.43°N, 76.70°E, dip 4°N) are found to have intense scintillations during daytime on some occasions. These daytime scintillation events are not associated with the q type of sporadic E layer as seen at Kodaikanal (10.23°N, 77.49°E, 3.5N) but are due to the intense ionisation patches in the E region indicated by occurrence on the ionograms of the non q type i.e. either high or flat type of sporadic E layer which either shows multiple reflections or blankets the higher reflections.
