| We emphasise on the solar radio observations in particular at hectometric, decametric and metric wavelengths. |
| The emissions we can hear are often referred to as decametric noise storms, because the waves are tens of meters long. |
| Narrowband spiky radio bursts, at decimetric and decametric wavelengths, with high degree of circular polarization are observed in solar flares. |
| This is one of the scientific objectives of the large decametric interferometer LOFAR, which should be operational in 2007 in Holland. |
| The decametric radiotelescope is dedicated to the study of comets, physics of galaxies, great structures of the Universe, pulsar chronometry. |
| A brief historical summary is followed by a review of current observations of Jupiter's decametric radiation. |
