Abstract.


The Solar and Heliospheric Observatory (SOHO), in halo 
orbit around the L1 Lagrangian point of the Sun-Earth 
system, combines a unique set of instruments for 
studies of the Sun and the Heliosphere. SOHO's Comprehensive 
Suprathermal and Energetic Particle Analyser (COSTEP) 
measures in-situ particles in the energy range 
44 keV/particle to above 53 MeV/n. For the time period 
of the Whole Sun Month Campaign in mid 1996 we have 
identified recurrent energetic particle intensity 
increases in association with co-rotating interaction 
regions (CIRs) in the energy range <10 MeV.
Solar wind measurements of the WIND spacecraft were 
used to estimate the corresponding magnetic source 
location in Carrington Longitude  for comparison of 
energetic particles with synoptic maps of the lower 
corona, derived from images of SOHO's Extreme Ultraviolet 
Imaging Telescope (EIT). The comparison reveals a 
close relationship of latitudinal extensions of polar 
coronal holes, situated in regions up to 40 deg away from 
the ecliptic, with CIR-associated in-ecliptic 
particle events.
