So far it is shown that there is an unsymmetry in the activity in the two hemispheres. The northern hemisphere is always more active than in the southern hemisphere except during the period of January to May 1970 which is the period of the maximum phase of the activity in the southern hemisphere. The whole activity was still the same as in the previous period.สาระสังเขป: (2) The active latitudes in the northern hemisphere in this period were lower than during the last period. There was one large group at latitude 19 degree in late October, the others were at latitudes 12-14 degree and 4 degree. The large group of class F at latitude 14 degree and longitude 34 degree in the middle of November disappeared at the west limb by the solar rotation on 22 November and reappeared on 5 December at the east limb. It lasted on the solar disk for more than 1 1/2 rotations.สาระสังเขป: (3) Mean seeing was poor, especially in December there were six cloudy days when observations were impossible. Authors
