We report data from the Cassini radio and plasma wave instrument during approach first orbit at Saturn. During approach, emissions Saturn showed that rotation period is now 10 hours 45 minutes +/- 36 seconds, about 6 longer than measured by Voyager in 1980 to 1981. In addition, many intense impulsive signals were detected lightning orbit. Some of these have been linked storm systems observed imaging instrument. Within magnetosphere, whistler-mode auroral hiss near rings, suggesting a strong...
An analytic one-dimensional magnetotelluric inversion scheme is described. The main characteristics of this new are its simplicity and minimal requirements in computer time storage space. basic idea the that for a given period T only structure above certain depth matters. therefore starts with shortest periods available data set tries to explain observed response, specifically apparent resistivity pa(T) phase ϕ(T), terms two-layer structure. Shifting successively longer periods, discrete...
This paper describes digital radio astronomical receivers used for decameter and meter wavelength observations. Since 1998, performing on-the-fly dynamic spectrum calculations or waveform data recording without loss have been at the UTR-2 telescope, URAN VLBI system, GURT new generation telescope. Here, we detail these developed operation in strong interference environment that prevails range. Data collected with allowed us to discover numerous objects phenomena low frequencies, a summary of...
Abstract Cassini flew past Jupiter in 2000/2001, and Juno has been orbiting the gas giant since mid‐2016. Here we focus on spectral properties of Jovian broadband kilometric radiation (bKOM), classified them according to their slope time–frequency spectrum distinguish four categories with negative, positive, mixed, or no frequency. These bKOM structures had mostly negative slopes during inbound portion flyby, whereas they were positive for outbound. The reason this could be higher...
Nanoplastics, plastic particles smaller than 1 micrometer, are an emerging contaminant of concern in aquatic ecosystems globally, including Africa. Monitoring the presence and impacts nanoplastics is crucial for continent given its reliance on fisheries aquaculture food livelihoods. Advanced electronic sensor technologies offer promising tools detecting quantifying water bodies, as well assessing their biological effects organisms. This review examines potential applications sensors, such...
The Radio and Plasma Wave Science (RPWS) experiment onboard the Cassini spacecraft collected electron density data in Saturn's magnetosphere during entire orbital phase of mission, comprising over 13 years data. Electron densities have been derived from observations electromagnetic plasma waves, like whistler-mode hiss electrostatic upper hybrid emissions, also a Langmuir probe, which measures potential as proxy to thin region. method based on wave has good coverage high exceeding 1 cm-3...
In one-dimensional magnetotelluric modelling the standard deviation ∊ is often used as an indicator of degree fit between field measurements and calculated model response. The topography in space parameters has been studied found to be rather simpler than expected. absolute minimum seems quite isolated from other minima. general no such local minima were found. To find it was not necessary, therefore, look for a computing routine capable jumping out localized But search had moving along...
The Radio and Plasma Wave Science instrument (RPWS) on board the Cassini spacecraft has detected numerous narrowband radio emissions in Saturn's magnetosphere from September 2005 to May 2007. Typically, occur after an intensification of Saturn kilometric radiation (SKR) last for several days. These often near 5 kHz, with a modulation period about 10.8 h, similar planet's rotation period. Other apparently associated bands also at higher frequencies, typically 20 30 kHz. Both kHz tend decrease...
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, night side August 17, 2009 at −36.4° ± 0.1° planetocentric latitude 10.6° 0.9° west longitude. No other locations produced detectable by either imaging or radio. The images are consistent with a single flashing once per minute. energy flash is comparable to that Earth Jupiter, ranges up 1.7 × 10 9 Joules. diameter flashes ∼200...
