                         solar and geomagnetic activity. In 1852, it was first noted that 
                         both the numbers of sunspots and geomagnetic storms at Earth have 
                         an 11 year cycle. A few years later, it was noted that a large 
                         magnetic storm followed the great September 1859 solar flare and a 
                         causal relationship between flares and storms was speculated. It 
                         was not until this century that a well-accepted statistical survey 
                         on large solar flares and geomagnetic storms was performed. The 
                         results indicated that a significant correlation between flares 
                         and geomagnetic storms exist.",
