The magnetosphere and ionosphere response to the SSC event at 24 January 2012 was investigated using complex of spacecraft and ground-based instruments. The SSC produce strong increase of the energetic particles fluxes (40 keV2 MeV), density, temperature inside the magnetosphere as seen by the THEMIS, COES spacecrafts. The SSC already is not shock wave in the outer magnetosphere (Mf ≈ 0.4). SSC produce the substorm development on the nightside during prolonged positive Bz-component of IMF and generation of Pc4-5 pulsations on the morning side. In the different MLT sectors of auroral zone SSC produce increase of the TEC (ΔTEC=20-30%), determined by the GPS receivers. This response was accompanied by the increase of the electron density at the altitudes 90-200 km as seen from the VHF EISCAT radar in Tromso. So the main contribution to TEC increase has the lower part of the ionosphere. Obviously the TEC response is caused the particle precipitation into the ionosphere. SSC produce strong increase of the CNA in Scandinavia and in Svalbard. The strong increase of the aurora intensity at different spectrum lines (420-700 nm) was registered by hyperspectral camera NARUSSCA II of the Polar Geophysical institute in Svalbard. The SSC produce strong increase of the GIC at electric power lines of the Kola Peninsula and Karelia (~30 A).
