Abstract

A REGULAR schedule of broadcasts of cosmic data and scientific news was inaugurated at Boston, U.S.A., on February 1 by the World Wide Broadcasting Foundation's short-wave station in co-operation with the Union Radio Scientifique International and Science Service. The primary purpose of these broadcasts is to make available internationally technical data on observations of sunspots, solar radiation, magnetism, ionized layer heights and other phenomena observed during the same day, and to interest laymen in making observations. The broadcasts will be heard daily from 4.55 to 5.00 p.m. (Eastern Standard Time) on 25-4 metres and weekly summaries on Monday evenings from 8.30 until 8.45 p.m. on 49-6 metres. The Monday evening broadcasts will be a weekly compilation. The programme inaugurating this service included brief talks by Dr. A. E. Kennelly of Harvard University, the co-discoverer of the Kennelly-Heaviside layer; Dr. Harlow Shapley, director of the Harvard College Observatory, and Watson Davis, director of Science Service, Washington.
