In situ data from the ACE satellite measuring the conditions of the solar wind close to Earth. Plotted are (from A to C) the total strength of the magnetic field, the B_x, B_y, and B_z component of this magnetic field, the solar wind speed, the proton density and the temperature. No clear signs of the arrival of an ICME are visible in the days after August 14, 2010. Images produced with http://omniweb.gsfc.nasa.gov/form/omni_min.html .
