Fig. 10

Half-day averaged variation of solar wind proton density, solar flow velocity, and IMF, geomagnetic indices in the case of “toward” (IMF Bx > 0 and By < 0) during solar cycle 23 and 24. The vertical light blue line represents the start time of an enhancement of solar wind velocity around the Earth’s orbit. The error bar represents the standard deviation
