1. Signatures of two distinct driving mechanisms in the evolution of coronal mass ejections in the lower corona / Assinaturas de dois mecanismos distintos na evolução de ejeções de massa coronal na baixa coroa
Coronal mass ejections (CMEs) are the major driver for space weather disturbances. Their physical mechanisms and their influence on the geospace environment are the subject of active research and debate. Our goal is to understand how the initial magnetic configuration of a CME affects its evolution through the lower corona, until 6R⊙. We compare ou

2. Signatures of two distinct driving mechanisms in the evolution of coronal mass ejections in the lower corona / Assinaturas de dois mecanismos distintos na evolução de ejeções de massa coronal na baixa coroa
As ejeções de massa coronal (coronal mass ejections - CMEs) são as maiores causadoras das perturbações do clima espacial. Seus mecanismos físicos e sua influência no ambiente geoespacial são foco importante em debates e pesquisas. Nosso objetivo é compreender como a configuraçãoo magnética inicial da CME afeta sua evolução na baixa coroa, até

3. Positive and negative sudden impulses caused by fast forward and reverse interplanetary shocks
Choques interplanetários do tipo frontal rápido (FFS) são caracterizados por uma descontinuidade súbita positiva em todos os parâmetros de plasma interplanetário (velocidade, temperatura e densidade do vento solar) e campo magnético interplanetário. Os choques do tipo reverso rápido (FRS) possuem descontinuidade súbita negativa em todos os parâmet

4. A study of single and compound interplanetary magnetic structure characteristics and their geoeffectiveness / Estudo de características e geoefetividade de estruturas magnéticas interplanetárias simples e compostas
The aim of this work is to study characteristics and geoeffectiveness of interplanetary shock waves, sector boundary crossings, magnetic clouds and combinations of these single interplanetary magnetic structures for the solar wind in situ observational period, from 1964 onwards. A seasonal variation in the interplanetary shock occurrence near Earth was found

5. Interplanetary shock parameters during solar activity maximum (2000) and minimum (1995-1996)
Interplanetary shock parameters are analyzed for solar maximum (year 2000) and solar minimum (years 1995-1996) activity. Fast forward shocks are the most usual type of shock observed in the interplanetary medium near Earth's orbit, and they are 88% of the identified shocks in 2000 and 60% in 1995-1996. Average plasma and magnetic field parameters for upstrea

6. A origem interplanetária e o desenvolvimento da fase principal das tempestades geomagnéticas moderadas (1978-1979) / The interplanetary origins and the main-phase development of moderate geomagnetic storms (1978-1979)
Geomagnetic storms are related to the ring current, which is driven by energy injection primarily during energetic solar wind-magnetosphere coupling due to reconnection at the magnetopause. This work identified the interplanetary origins of moderate geomagnetic storms (-100 nT

7. The interplanetary origins and the main-phase development of moderate geomagnetic storms (1978-1979) / A origem interplanetária e o desenvolvimento da fase principal das tempestades geomagnéticas moderadas (1978-1979)
Geomagnetic storms are related to the ring current, which is driven by energy injection primarily during energetic solar wind-magnetosphere coupling due to reconnection at the magnetopause. This work identified the interplanetary origins of moderate geomagnetic storms (-100 nT < DstMíN < -50 nT) and analysed the coupling processes during the storm mai
