Abstract

THE large, sudden increase in cosmic-ray intensity between the hours 0300 and 0400 G.M.T. on February 23 was observed at Hobart, Tasmania, Australia, and also at the Australian National Antarctic Research Expedition's bases at Macquarie Island and Mawson, Antarctica. At the same time radio fade-outs, ionospheric and magnetic disturbances were recorded. The cosmic-ray increase resembles those observed in other places on four previous occasions in association with solar flare activity, namely, on February 28 and March 7, 1942, July 25, 1946, and November 19, 19491.
