Using two aircraft as mobile geomagnetic observatories to study the similarity of pulsations (2 – 25 s) as a function of aircraft separation (1.6 – 4600 km), an analysis appears to show that pulsation correlation decreased dramatically at a separation corresponding roughly to the heigh of the ionosphere.
