%X Wide-band bursts of radio noise from the upper ionosphere or exosphere have been observed at frequencies from 100 cIs to 250 kc/s. The observed intensity [Wm-2 (C/S)-I] ranges from nearly 10-9 at 100 cIs to 10-19 at 250 kc/s. However, the intensity at the source (above the ionosphere), deduced by subtracting the losses suffered in the ionosphere and below the ionosphere, shows a relatively flat spectrum at a level of the order of 10-10 Wm-2 (C/S)-I.
