Sun-Spots and Magnetic Storms

Abstract

SOME particulars of the remarkable double outburst of sun-spots in the latter part of April and of the magnetic disturbances which appear to have been connected with them, as recorded at Greenwich, may be of interest to your readers. It is in itself a noteworthy fact that there should be on the sun at the same time two spots, one of them double, sufficiently large to be visible to the naked eye, and this is made still more interesting by the occurrence of a violent magnetic storm a few days after the appearance of each of these large spots.
