The 12-month running mean of the geomagnetic index aa seems to have attained a minimum value of 17.5 centered at December 1986. The fresh estimate of Rz(max ) is now ~ 165 \_+ 35. Also, if Rz(min ) is taken into consideration, the Rz(max ) estimate will drop to ~ 130. Details of the methodology and

Examined are associational aspects as they relate the maximum amplitude R M for the sunspot cycle to the rate of rise Ral during the ascending phase, where R M is the smoothed sunspot number at cycle maximum and Rat is the sum of the monthly mean sunspot numbers for selected 6-month intervals (At) m
