摘要: Here we present the study of daytime scintillation due to E region irregularities at low latitudes from a set simultaneous observations on June 3, 1993. The effects these are clearly seen (1) 103 MHz signal radio star 3C 196 recorded Rajkot and Thaltej (near Ahmedabad, India), (2) 244-MHz beacon Fleetsat satellite (73°E) (3) ionosonde being operated Ahmedabad. These provide an estimate irregularity patch with spatial extent around 400 km east-west 80 north-south. As subionospheric points source quite far apart, dynamics is also possible which indicates southward movement patch. drift speed ∼ 60 m/sec calculated upper frequency roll off spectrum MHz. This found be consistent earlier investigations blanketing Es near magnetic equator.
