It has been shown that the sporadic E configuration observed in the ionograms from equatorial stations can suddenly appear or disappear in a time period of one minute or less. Such short decoy (or growth) times are found to agree with theoretical estimates of cross‐field instability calculations. These findings further support the identification of Es‐q to cross‐field instabilities. Attempts should be made to study the real time evolution of these irregularities by backscatter radars or finer time resolved ionosondes.
