                         events that occurred during pre- and post-sunrise hours in the 
                         South America sector on 18 March 2015, when the St. Patrick's Day 
                         geomagnetic storm was in the recovery phase. The data from a set 
                         of multi-diagnostic instruments, including Global Navigation 
                         Satellite Systems (GNSS) receivers, L-band GNSS ionospheric 
                         scintillation monitors, ionosondes, and a Fabry-Perot 
                         interferometer, are analyzed. Strong L-band amplitude 
                         scintillation was observed with spread-F and total electron 
                         content (TEC) fluctuations at times when the electron density and 
                         tTEC were minimum with respect to their diurnal variations. The 
                         EPBs remained observed for about 3:30 hr after sunrise on the east 
                         coast of the South American continent. The daytime ionospheric 
                         irregularities show a longitudinal dependency between the west and 
                         east coasts, separated by about 3,600 km. Our analysis of the 
                         observations suggests that a Disturbance Dynamo Electric Field 
                         effect caused by storm-time wind perturbations might have 
                         triggered the Rayleigh-Taylor instability near local dawn on the 
                         east and west coasts of the South American continent. The effects 
                         of ambient ionosphere-thermosphere conditions on the evolution of 
                         irregularities are assessed to understand the longitudinal 
                         differences. The assessment includes the effect of the E region 
                         that appears in the morning hours and the effects of geomagnetic 
                         declination and tilting the solar-terminator.",
