By a sample record we show that the radio beacon experiments which utilize the Faraday rotation technique and the scintillation observations can be used to observe equatorial ionization bubbles. In a two‐hour period 5 isolated bubbles have been identified. The depleted total electron content for one such bubble is 2.2×10 16 electrons/m² and the east‐west dimension is about 72 km. This translates to a total depletion of 1.6×10 21 electron per meter in the north‐south direction.
