Solar wind parameters for the period 27 November 2011, 00:00 UT–08 December 2012, 12:00 UT (CR 2117). The dash-dotted lines implicate the predicted period of the HSS arrival to the Earth. The dotted lines correspond to: in the proton temperature graph − the expected temperature, in the magnetic field graph − B_z component. The solid vertical line shows a shock. The solar wind phenomena marked by the color bars are: HSSs (blue bar), ICMEs (green bar), CME-HSS interaction regions (red bar).
