Electron spike on 2 May 2014. Top: spike intensity time profiles detected at STEREO-A (red) and STEREO-B (blue) with SEPT-Sun telescope viewing in the sunward direction, showing very similar spike + ramp shapes in the energy range of 55–65 keV. STEREO-B measured a higher intensity and an earlier onset compared to STEREO-A. Bottom: intensity pitch angle distribution divided in four bins (=4 telescopes). White intervals denote sectors with no pitch angle coverage.
