abstract = "In this work, we observe for the first time the unusual
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 un- common 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
\̃ao 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 \̃ao Lu{\'{\i}}s and Eus \́ebio
(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 h. Finally, we showed that
these EPBs are likely driven by a disturbance wind dynamo effect,
which helps to un- derstand the role of the external factors in
EPBs development.",
