Abstract
THE giant sunspot which crossed the sun's disk between October 5 and 18 broke up before its return, due at the eastern limb on November 2. Meanwhile, another large spot had formed in solar longitude 273° and in latitude 9° south. This spot came round the limb on November 4, though it was not completely seen until the following day, when its area was 2000 millionths of the sun's hemisphere. The time of central meridian passage was November 10· 8 U.T. ; its date of disappearance around the western limb will be November 17.
