Two high-altitude atomic explosions which were set off over Johnston Island in the Pacific in August 1958 appear to have had a rather pronounced effect on the radio noise as recorded at Kekaha, Hiwaii. Atmospheric radio-noise received for a period before and after the first explosion is shown. In the hour following the blast the noise decreased by as much as 32 db. ai a time of day when it would normally be rising or holding steady. Recovery apparently occurred in a matter of hours at 13 kc/s. and 5 Mc/s., but from 51 kc/s. to 2.5Mc/s. a changed pattern was evident for several days with levels at night much below normal.
