During the NASA mobile launch expedition when rocket experiments were conducted at various latitudes, the presence of various types of sporadic-E was noticed on the corresponding ionograms. Careful examination of data from a DC probe showed that irregularities of ionization having spatial periods of approximately 75-270 m with amplitudes greater than 10 per cent of the ambient density existed whenever diffuse non-blanketing sporadic-E was present. Such irregularities were also noticed during the equatorial launching (close to the magnetic equator) in the altitude range 90-100 km with an amplitude of about 12 per cent. It is suggested that these irregularities are responsible for the equatorial Es or q-type Es reflection seen in the ionograms. It appears that irregularities closer to the E-region peak, having larger amplitudes and smaller spatial periods are more effective in producing this non-blanketing type of sporadic-E. Of the various sporadic-E parameters, fbEs rather than fEs is a better measure of the peak electron density in the ledges of ionization appearing in the E-region. These observations suggest the existence of two types of Es: one consisting of overdense ledges of ionization and the other of underdense irregularities of ionization.
