                         2000-2002, all solar indices (including EUV) had two maxima. one 
                         near July 2000 and another near end of 2001. but the magnitudes of 
                         the second maximum relative to the first maximum were different 
                         for different solar indices. For EUV 26-34 nm relevant for 
                         ionospheric (foF2)(2), the second maximum was similar to 3% higher 
                         than the first maximum. The 12-month running means of (foF2)(2) at 
                         some mid-latitude locations in both hemispheres showed similar two 
                         maxima, but the magnitudes of the second maximum relative to the 
                         first maximum were not similar to those of observed solar EUV 
                         (similar to 3%) and were very different at different locations 
                         (-3% to + 18%). Even on the solar cycle time scale (solar minimum 
                         to solar maximum), changes of (foF2)(2) at different locations 
                         were not alike (factors of 3.1-4.5).",
