The longitudinal position of a spacecraft relative to that of the active region associated with a solar energetic particle (SEP) event is known to have a strong impact on the characteristics of the temporal profile of the observed particle intensities. It is still debated as to whether the composition of the SEP event is similarly impacted. Most compositional studies have been done with single point measurements (typically near L1) and statistical analysis of the active region solar longitudes. With the twin STEREO spacecraft significantly separated from L1-based satellites such as ACE, simultaneous multi-point measurements of SEP events can be made for H-Fe ions from a few hundred keV/n to over 10 MeV/n and for electrons from tens to hundreds of keV. Additionally measurements of associated solar phenomena, e.g., coronal mass ejections, radio bursts, and solar flares can be made from distinctly different vantage points. Here we present particle data from instruments on STEREO and ACE for the recent SEP events of solar cycle 24 and compare their characteristics to the positions of the spacecraft relative to the solar source regions. The solar context for these events will also be discussed as measured by STEREO, SOHO, SDO, and Wind.
