| Zusammenfassung |
| Lightning-generated radio emission from Saturn has been observed by satellite missions
(1980, 1981, and since 2004) and from the ground (since 2006). The detection of SED allows
to study electrification processes, atmospheric dynamics, geographical and seasonal
variations. Using a new broadband receiver at UTR-2 (Ukraine), Saturn lightning was
detected over the whole spectral range of the instrument (10-30 MHz) in December 2007. For
the first time, this allowed to study the instantaneous spectrum of the discharge,
and the temporal fine structure of the emission could be studied with a temporal
resolution surpassing that of regular satellite observations. The complementarity of
ground-based and space-borne observations is discussed, and future observation plans are
presented. |
