%3 Abstract ILWS2009 An analysis of the geomagnetic field variation due to solar flare Tardelli Ronan Coelho Stekel.doc
%B International Living with a Star, (ILWS/2009).
%X The solar flare incidence follows a behavior similar to the solar cycle activity, which results in periodic disturbances on the Earths atmosphere and magnetosphere. Sudden perturbations of the geomagnetic fields at solar flares are called geomagnetic Solar Flare Effect (SFE) or Magnetic Crochet. The SFE is associated with the sudden change of ionospheric currents caused by the extra ionization produced by the soft X-ray (0.1 to 9.0 nm) and EUV (9.0 to 100.0 nm) radiation from the solar flare. Ten (10) intense SFE events were analyzed for the horizontal (H), declination (D) and vertical (Z) geomagnetic component from 2001 to 2004. For this purpose, analysis were performed for X-ray data (0.1 to 0.8 nm) from the GOES X-ray Sensor (XRS), positioned inside the geomagnetic field, and the EUV data (26.0 to 34.0 nm and 0.1 to 50.0 nm) from SOHO Solar Extreme Ultraviolet Monitor (SEM), located outside the geomagnetic field, as well as, the magnetometers data dedicated to study of the Solar-Earth interactions at the Southern Space Observatory (SSO/CRS/INPE  MCT), (29.4°S, 53.8°W), São Martinho da Serra, RS, Brazil. With the analyze of these events it was made the correlation between the solar flare and the magnet crochet event studying the direction of ionospheric current and the importance of the solar terrestrial relationship.
