                         pre-sunrise Equatorial Plasma Bubbles (EPBs) during a moderate 
                         geomagnetic storm recovery phase caused by the High-Speed Solar 
                         Wind Stream (HSS) on February 17, 2015, over the Brazilian sector. 
                         Therefore, this study aims to explain the generation mechanism of 
                         this uncommon event, which started at 08:00 UT on February 18, 
                         2015. We used Multiple Global Navigation Satellite Systems 
                         (Multi-GNSS, GPS, and GLONASS) data to produce two-dimensional 
                         maps of the Rate Of TEC index (ROTI) that show EPB features 
                         elongated in magnetic meridians. Also, Digisonde data from 
                         S{\~a}o Lu{\'{\i}}s (2.53° S, 44.30° W, dip angle: -8.57°), Boa 
                         Vista (12.81° N, 60.67° W, dip angle: 33.71°), and Campo Grande 
                         (20.44° S, 54.64° W, dip angle: -25.98°), and magnetometer data at 
                         S{\~a}o Lu{\'{\i}}s and Eus{\'e}bio (3.89° S, 38.45° W, dip 
                         angle: -17.96°). Our analysis shows that the unusual pre-sunrise 
                         plasma bubbles lasted longer after sunrise, around 1 hour. 
                         Finally, we showed that these EPBs are likely driven by a 
                         disturbance wind dynamo effect, which helps to understand the role 
                         of the external factors in EPBs development.",
