                         follows a trend similar to that of sunspot numbers during the 
                         rising and maximum phase of the solar cycle. In the declining 
                         phase, the CME number has large fluctuations, dissimilar to those 
                         of sunspot numbers. In several studies of solar -aEuro parts per 
                         thousand interplanetary and solar -aEuro parts per thousand 
                         terrestrial relationships, the sunspot numbers and the 2800-MHz 
                         flux (F10) are used as representative of solar activity. In the 
                         rising phase, this may be adequate, but in the declining phase, 
                         solar parameters such as CMEs may have a different behaviour. 
                         Cosmic-ray Forbush decreases may occur even when sunspot activity 
                         is low. Therefore, when studying the solar influence on the Earth, 
                         one has to consider that although geomagnetic conditions at solar 
                         maximum will be disturbed, conditions at solar minimum may not be 
                         necessarily quiet.",
