                         storm due to the St. Patrick's day storm and the effects of this 
                         storm on ionosphere has become a topic of extensive space weather 
                         investigation. Up to now several aspects of the St. Patrick's 
                         ionospheric storm have been study such as the prompt penetration 
                         electric fields (PPEFs), TEC changes, electron density 
                         disturbances, plasma drift, O+ concentration modification, 
                         hemispherical asymmetry developments, equatorial ionization 
                         anomaly (EIA) modification, 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, 20 dual 
                         frequency GPS stations, and JULIA radar observations during the 
                         month of March 2015, which includes the St. Patrick's 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 first night of 
                         recovery phase there was post-midnight ionospheric
