Cross-correlation analyses between galactic cosmic-ray intensities fro
m Calgary neutron monitor and several solar-activity parameters, on da
ily basis, have been undertaken, We report here results connected with
the unresolved full-solar X-Ray background and the occurrence of sola
r LDE-type flares (both from GOES-satellite data) in the time interval
July 1988-June 1989 (i.e. the last part of the ascending phase of sun
spot cycle 22). Our findings do not support the hypothesis that LDE-ty
pe flare occurrence is the best parameter to describe the medium-term
modulation of galactic cosmic rays; however, it could be a good indica
tor of sudden but stable coronal variations occurring along the solar-
activity cycle, i.e. a proxy data set to include peculiar transient-in
duced effects on the long-term cosmic-ray modulation studies.
