Radio Astronomy at Long Wavelengths

The first reports back from what has until now been an unexplored region of the radiomagnetic spectrum, from 30 kHz and a wavelength of ten kilometers to about 30 MHz and a wavelength of ten meters, three orders of frequency magnitude just below the standard radion astronomy region. The 36 tutorials and reviews from an October conference in Paris, France consider the generation of radio waves, propagation and scattering, long wavelength radio emission from the solar system and from galactic and extragalactic sources, and radio telescopes for long wavelength observations and sounding. They include a few color plates, but are not indexed. Annotation c. Book News, Inc., Portland, OR (booknews.com)
