The 23 July 2012 CME from three views and the >10-MeV particle flux. Three snapshots of the 2012 July 23 backside event taken around the same time: (a) STB, (b) SOHO/LASCO, and (c) STA. The CME was heading toward STA, so it appears as a symmetric halo. (d) >10 MeV flux at STA, STB, and GOES. The separation angle of STA and STB from Earth are given in (d).
