SUNSPOTS
ABNORMAL ACTIVITY OBSERVED WELLINGTON, Dec. 23. “Since the beginning of November conditions on tbe sun have been extremely disturbed,” stated Mr G 1L Hudson, of Karori, to-day. “During most of this period there has been analmost continuous series of sunspots. Two large gr/oups of highly active spots have recently entered the disc and will pass the central meridan towards the end of this week. The photosphere around these spots is much disturbed and there are many ‘faculae.’ Numerous smaller spots extend from this group across the sun to its western limb. “During last week a number of large sunspots passed out of sight around the western limb, so that apparently great activity exists upon the spot zones round the entire sun. This state of affairs is distinctly abnormal, as we should be approaching the time when the spots diminish in accordance with the well established eleven-year cycle. In August and September there was certainly a substantial decrease in solar activity as might have been expected in the ordinary course, but that has been followed by the present abnormal increase.”
