Space Weather conditions during 8th September 2017, shown with common parameters. Top panel: solid line is geomagnetic SYM-H index. Bars indicate occurrence of solar flares. Second panel: Auroral electrojet index derived from IMAGE magnetometers (IE). Third panel: solar wind speed (SW). Fourth panel: Y and Z-components of the interplanetary magnetic field (By, Bz) in the geocentric solar magnetospheric (GSM) coordinates. Last panel: Solar wind flow pressure (SWfp). The solar wind data presented herein corresponds to the 1-min averaged values and involves the Earth’s bow shock nose shifted ACE and WIND data available from the NASA’S OMNIWeb data service (http://omniweb.gsfc.nasa.gov/).
