Previous comparisons of solar energetic particle (SEP) events at 1 AU with associated coronal mass ejections (CMEs) have shown a correlation between peak SEP fluxes and CME speeds. These results have provided some of the evidence for acceleration of SEPs by CME-driven shocks. We compare SEP observations from the Helios spacecraft with associated CME and shock speeds reported by Sheeley et al. (JGR, 1985). We find that the 3 < E < 6 MeV peak proton fluxes correlate better with the in situ shock speeds than with either the CME speeds or the average transit speeds of the shocks. This establishes a closer physical connection between SEPs and CME-driven shocks than the previous work which used CME speeds as rough proxies for the shock speeds. We also examine the speed profiles of a number of fast CMEs observed with the SOHO LASCO coronagraph to look for distinguishing characteristics of CMEs associated with SEPs at 1 AU.
