The radio beacon signals on 40 MHz, 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, 3.5 N) 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. |
