Paper Abstract

We studied the 557,7 and 630-nm atomic oxygen emission responses to the solar wind sharp variations caused by shocks. For the analysis, were used optical and geomagnetic data for the Eastern Siberia and interplanetary magnetic field and solar wind data. The considered emission intensity was found to increase for some cases, whereas, in other cases, there were no responses during sharp variations in solar wind plasma speed and density. The presence or absence of the responses in the emissions was shown to be not related to the disturbance amplitude of the solar wind parameters. We suggested that the emission intensity increase might be caused by electron precipitation from the magnetic trap during the interaction between the solar wind shock and the magnetosphere.
