                         Digisondes operating near the launching sites revealed a rapid 
                         rise in the F-region base indicating a probable pre-reversal 
                         enhancement of the vertical plasma drift. Strong spread-F traces 
                         are also visible on the ionograms simultaneously recorded, 
                         suggesting the occurrence of ionospheric bubbles during these 
                         campaigns. Electron density and temperature vertical profiles 
                         estimated from the LP data exhibit in the E-F region valley
