  The study of the solar energetic particle events (SEPs) and their association
with solar flares and other activities are very crucial to understand the space
weather. Keeping this in view, in this paper, we present the study of the SEPs
(intensity equal to or greater than 10 pfu) during the solar cycle 21 to 24
(1976-2017) in > 10 MeV energy channels associated with solar flares. For our
analysis, we have used the data from different instruments onboard SOHO
satellite. We have examined the flare size, source location, CMEs
characteristics of associated SEPs. About 31% and 69% of the SEPs were
originated from the eastern and western solar hemisphere respectively. The
average CME speed and width were 1238 km/s and 253 deg respectively. About 58 %
SEPs were associated with halo CMEs and 42% of SEPs associated with CMEs width
varying from 10 deg to 250 deg respectively.
