We present our results on the correlation of non-interacting coronal massejections (CMEs) and solar energetic particles (SEPs). A statistical analysiswas conducted on 25 SEP events and the associated CME and flare during theascending phase of solar cycle 24, i.e., 2009-2013, which marks the quadratureconfiguration of Solar TErrestrial RElations Observatory (STEREO). The completekinematics of CMEs is well studied near this configuration of STEREO. Inaddition, we have made comparison studies of STEREO and SOlar and HeliosphericObservatory (SOHO) results. It is well known that the CME speeds and SEPintensities are closely correlated. We further examine this correlation byemploying instantaneous speeds (maximum speed and the CME speed and Mach numberat SEP peak flux) to check whether they are a better indicator of SEP fluxesthan the average speed. Our preliminary results show a better correlation bythis approach. In addition, the correlations show that the fluxes of protons inenergy channel >10 MeV are accelerated by shock waves generated by fast CMEs,whereas the particles of >50 MeV and >100 MeV energy bands are mostlyaccelerated by the same shock waves but partly by the associated flares. Incontrast, the X-ray flux of solar flares and SEP peak flux show a poorcorrelation.
