             abstract = "During the solar cycle 24 there was a very intense geomagnetic 
                         storm called the St. PatrickZs Day storm and the eects of this 
                         storm on ionosphere has become a topic of extensive space weather 
                         investigation. Up to now several aspects of the St. PatrickZs 
                         ionospheric storm have been study such as the prompt penetration 
                         electric elds (PPEFs), GPS-TEC changes, electron density 
                         disturbances, plasma drift, O+ concentration modication, 
                         hemispherical asymmetry developments, equatorial ionization 
                         anomaly (EIA) modication, and ionospheric irregularities. Besides 
                         all these important studies, there are some essential aspects, 
                         which have not been addressed yet, related to the occurrence of 
                         multi-scale ionospheric irregularities. In this paper, we present 
                         and discuss the generation and suppression of multi-scale 
                         ionospheric irregularities, using the observations conducted in 
                         the Latin American Sector from 4 ionosondes (ESF) and 20 GPS-TEC 
                         stations (ROT phase uctuation) observations during the month of 
                         March 2015, which includes the St. PatrickZs Day geomagnetic storm 
                         period. Suppression of large-small scales ionospheric 
                         irregularities has occurred during the main and second night of 
                         the recovery phases. However, during the rst night of recovery 
                         phase there was post-midnight ionospheric irregularities.",
