The Sun was very active in the early part of November 2004. During the period of 8-10 November 2004, intense geomagnetic disturbances with two superstorms were observed. In a companion paper (hereafter referred to as Paper I), the effects observed in the F-region, during the intense geomagnetic disturbances in the early part of November 2004 in the Latin American sector were presented. ...
The Sun was very active in the early part of November 2004. During the period of 8-10 November 2004, intense geomagnetic disturbances with two superstorms and two intense geomagnetic storms were observed. In this paper, we present the ionospheric sounding observations carried out at Manaus and Sao Jose dos Campos, Brazil, during this geomagnetically disturbed period. Also, GPS observati...

The objective of the project is to study space weather events and their influence on the ionospheric F region in the Brazilian sector. It is proposed to use the ionospheric sounding and GPS (Global Positioning System) data obtained by the UNIVAP network with digital ionosondes and GPS receivers co-located at S.J. Campos (23.2º S, 45.9º W), Palmas (10.2º S, 48.8º W) and Manaus (2.9º S, 6...
