Analysis of a long-lived, two-cell lightning storm on Saturn
Lightning storms in Saturn’s atmosphere can last for a few days up to several months. In this paper we analyze a lightning storm that raged for seven and a half months at a planetocentric latitude of
Lightning storms on Saturn observed by Cassini ISS and RPWS during 2004–2006
Overview of Saturn lightning observations
The lightning activity in Saturn's atmosphere has been monitored by Cassini for more than six years. The continuous observations of the radio signatures called SEDs (Saturn Electrostatic Discharges)
Lightning and Thunderstorm Observations by Cassini and Voyager Spacecraft at Saturn
Indication for the existence of lightning in Saturn's atmosphere was first obtained in November 1980 by the radio instrument on-board Voyager 1 which recorded strong impulsive radio signals. The same
Polarization measurements of Saturn Electrostatic Discharges with Cassini/RPWS below a frequency of 2 MHz
[1] Early in 2006 the RPWS (Radio and Plasma Wave Science) instrument and the ISS (Imaging Science Subsystem) onboard the Cassini spacecraft detected a lightning storm on Saturn that lasted for about
A giant thunderstorm on Saturn
Observations of a giant thunderstorm at planetocentric latitude 35° north that reached a latitudinal extension of 10,000 kilometres about three weeks after it started in early December 2010, which developed an elongated eastward tail with additional but weaker storm cells that wrapped around the whole planet by February 2011.
The Great Saturn Storm of 2010–2011
In December 2010, a major storm erupted in Saturn's northern hemisphere near 37 degree planetographic latitude. This rather surprising event, occurring at an unexpected latitude and time, is the
Ground-based study of Saturn lightning
Radio signatures of lightning discharges on Saturn have first been discovered by the Voyager spacecraft in 1980/81. After the Voyager flybys, the next sets of measurements only became available in
Detection of visible lightning on Saturn
Until now, evidence for lightning on Saturn has been indirect – through radio emissions and cloud morphology. Here we report the first visible detection of lightning, on the night side on August 17,


Cassini RPWS and Imaging Observations of Saturn Lightning
The Radio and Plasma Wave Science (RPWS) instrument on Cassini began observing Saturn Electrostatic Discharges (SED) on a routine basis on 13 July 2004, shortly after Saturn orbit insertion (SOI).

Atmospheric storm explanation of saturnian electrostatic discharges
The Voyager Planetary Radio Astronomy (PRA) experiments detected an impulsive (15–400 ms), broadband (20 kHz to 40 MHz) radio emission component that persisted throughout the two Saturn encounter
Saturn's electrostatic discharges - could lightning be the cause
Effects of ring shadowing on the detection of electrostatic discharges at Saturn
A long‐standing discrepancy exists in determinations from observations and modeling of the diurnal variation of the peak electron density of Saturn's ionosphere. Using a new
Planetary Radio Astronomy Observations from Voyager 2 Near Saturn
While crossing the ring plane at a distance of 2.88 Saturn radii, the spacecraft detected an intense noise event extending to above 1 megahertz and lasting about 150 seconds, interpreted to be a consequence of the impact, vaporization, and ionization of charged, micrometer-size G ring particles distributed over a vertical thickness of about 1500 kilometers.
Statistical study of Saturn electrostatic discharges
During the Voyager Saturn mission the Planetary Radio Astronomy (PRA) experiment observed sporadic broadband emissions (20 KHz to at least 40 MHz) during a few days around the Voyager 1 and 2 closest
Saturn's ionosphere: Inferred electron densities
During the two Voyager encounters with Saturn, radio bursts were detected which appear to have originated from atmospheric lightning storms. Although these bursts generally extended over frequencies
