In Dec. 2006, single sunspot region produced a series of proton solar flares, up to X9.0 level on 5 Dec 2006 10:35 UT. One unique feature of this X9.0 flare is that MeV particles originated from this proton flare were observed at Venus and Mars by Venus Express (VEX) and Mars Express (MEX), which are respectively located away from Earth by nearly +160° and -160° as viewed from the Sun. On 5 Dec 2006, the plasma instruments ASPERA-3 and ASPERA-4 on board MEX and VEX have detected a large enhancement in their respective background count level, which is a typical signature of intensive MeV particle flux. The timing of these enhancements were consistent with the estimated field-aligned travel time along the Parker spiral from the site of X9.0 flare to Venus and Mars. The Mars Express data indicate a one-order enhancement in the heavy ion outflow from the Martian atmosphere during the SEP period. This is the first observation of the increase of escaping flux at Mars during a violent solar activity. This suggests that the solar EUV flux levels also significantly affect the atmospheric loss from unmagnetized planets.
