                         CR (Cosmic Ray) intensity and solar, interplanetary and 
                         terrestrial parameters. The hysteresis loops of (CR) versus those 
                         of several solar parameters showed narrow loops in even cycles 20, 
                         22 and broad loops in odd cycles 19, 21, as also in the recent odd 
                         cycle 23. Hysteresis plots for CR versus interplanetary number 
                         density N and speed V were erratic and uncertain (broad and 
                         narrow, all mixed up). Plots of CR versus Interplanetary magnetic 
                         field (IMF) B seemed to be narrow for even as well as odd cycles. 
                         Hysteresis loops between CR and other interplanetary parameters 
                         were not clear-cut. The same was true for terrestrial parameters. 
                         During sunspot maximum years 20002003 of cycle 23, there is a 
                         double peak structure in all parameters. Whereas CR have a peak 
                         spacing of 30 months, sunspots and Tilt angle have a spacing of 
                         only 20 months. The solar open magnetic flux and the Voyager 1 
                         magnetic field have a spacing of 25 months. The solar polar 
                         magnetic field reverses later than the first peak of all 
                         parameters and hence, could not be a direct cause (as if effect 
                         started before the cause and lasted for several months more after 
                         the cause disappeared). It seems that CR modulation is mainly 
                         guided by magnetic configurations deep in the heliosphere, which 
                         may not have a simple relationship with parameters near Earth or 
                         near Sun.",
