Upstream events are energetic particles that escape from or through the earth's bow shock into interplanetary space, with energies extending up to ~1 MeV. Despite having been observed for several decades, there is still no consensus on whether these events originate from the magnetosphere or the bow shock. Recent observations by the Wind spacecraft have shown that geomagnetic disturbances caused by CIRs are especially efficient at producing upstream events, but CMEs often do not produce them in any significant numbers. In this talk, preliminary results will be presented from an investigation of upstream events observed during solar maximum conditions, using data from the Wind and ACE spacecraft. In addition, the occurrence of upstream events during geomagnetic disturbances will be compared with the state of the magnetosphere in order to identify what aspects of geomagnetic activity, if any, are associated with the production of upstream events, and which indicators best characterize them.
