Abstract: Extreme events originating on the Sun induce various processes in the heliosphere, such as shock waves and particle acceleration. In this work, we studied the impact of extreme solar events on the flux of energetic particles measured at Lagrange point L1. In many cases, the enhanced flux of energetic particles can be clearly associated with a specific source and involves a well-known acceleration mechanism. However, in some instances, this connection is not as easily established. We examined and compared structures in energetic proton time series where a clear source is not immediately obvious, with structures clearly related to the concurrent passage of an ICME by analyzing the event-integrated fluence of energetic protons during November 2001 to potentially gain insight into the origin of such events.
