Abstract
SUN-SPOTS.—In the March number of the Memorie della Società degli Spettroscopisli Italiani, there are some interesting notes relating to spots and prominences. Prof. Tacchini gives a tabulated statement of the solar observations made at the Royal Observatory for the last three months of the year 1891. The most frequent records of faculæ occurred in the zones ± 10° ±30°, only one being seen as high as the zone + 40° + 50°. As regards the spots, the greatest frequency of groups took place in the zones ± 10° ± 20°, 23 and 10 being observed in the north and south respectively.
