Wireless Telegraphy and Solar Eclipses

Abstract

JUST before the beginning of the war in 1914 the Radiotelegraphic Committee of the British Association, which was appointed at the Dundee meeting in consequence of a suggestion by me, had, completed arrangements for certain observations to be made on the strength of radiotelegraphic signals on the line of totality of the 1914 solar eclipse which passed through Russia. These arrangements were rendered useless by the outbreak of the war. On May 29 of this year a total solar eclipse will be visible in North Brazil, and it seems very desirable that any eclipse expeditions sent out to observe it should be provided with wireless telegraph apparatus, and should arrange to receive, and also to send, signals to other stations before, during, and after the passage of the moon's shadow.
