SOLAR ECLIPSE
PHOTOGRAPHING CORONA IMPORTANT TESTS (British Official Wireless. — Copyright) RUGBY,' Thursday. The president of the British Astronomical Association, Dr. Stevenson, has gone to Zermatt, in Switzerland, in order to test whether the sun’s corona can be photographed in ordinary light. Dr. Stevenson, whose instruments were set up in the camp of the Astro-nomer-Royal, Sir Frank Dyson, at Giggleswick, during the recent total eclipse of the sun, is supported by Sir Frank in his belief that the corona was then visible for three minutes after the eclipse. The present tests will extend over a fortnight, during which a series of photographs will be taken from an altitude of 10,000 ft. with a highlycomplicated camera, in which the photographic plate will be shielded by a disc. The rays of the sun will pass through a filter and lenses will be used to prevent diffusion of light. Scientists attach much importance to the experiments, which, if successful, will greatly advance astronomical knowledge.—A. and N.Z.
