Abstract
THIS communication presents a preliminary account of the magnetotelluric and very low frequency signatures associated with the U.S. high-altitude nuclear detonations of October 20 (0830 : 00 G.M.T.), October 26 (0959 : 49 G.M.T.), November 1 (1210 : 06 G.M.T.), and November 4 (0730 : 00 G.M.T.) 1962, observed at our field station near Rochester, New York. Three orthogonal components of dB/dt in the band 0.001 to 3 c/s were sensed with cored loop antennæ of sensitivity 0.07 mV-sec/γ. A pair of electrodes spaced 225 ft. apart sensed the north–south component of the telluric-current field in the same band. A whistler-recording apparatus furnished a broadband very low frequency noise record.
