A Large Sunspot

Abstract

A BRIEF scrutiny of the sun's disk on January 15, made possible at Greenwich in a break of persistent cloud, showed that a big sunspot had appeared. The approximate time of the central meridian passage was January 18·4, the latitude of the spot being 19° N. ; its area was estimated to be about 2,500 millionths of the sun's hemisphere. The spot, which resembles the giant spot of last October, will reach the sun's western limb on January 24. A magnetic storm was recorded at Abinger commencing on January 16 at 22·6h.
