Initial observations by the Pioneer Venus magnetometer on the nightside of Venus frequently reveal moderately strong fields from 20 to 30 nanoteslas. However, there is little evidence that thesefields arise from an internal dynamo since they are mainly horizontal and vary from orbit to orbit. Determining a precise upper limit to the intrinsic moment awaits further processing. This limit is expected to be much less than 1022 gauss-cubic centimeters. 
Induced magnetosphere and its outer boundary at Venus
The induced magnetosphere at Venus consists of regions near the planet and its wake for which the magnetic pressure dominates all other pressure contributions. Initial Venus Express measurements
An induced global magnetic field looping around the magnetotail of Venus
Venus serves as the prototype of solar wind interaction with unmagnetized planetary bodies with atmospheres. It has no intrinsic dipole or crustal magnetic field; the only magnetic field is believed
Large amplitude nonlinear waves in Venus magnetosheath
Large‐amplitude variations of the magnetic field in the Venusian magnetosheath are observed when the distance between the bow shock and the magnetic pileup boundary is small, of the order of the ion

Introduction provided evidence for lightning at Jupiter. Dynamic spectra from the Voyager radio astronomy The studies of magnetospheric plasma waves in experiments obtained near Jupiter showed
The solar wind interaction with Venus - Pioneer Venus observations of bow shock location and structure
Pioneer Venus observations are used in conducting a study of the location and structure of the Venus bow shock. The trace of the shock in the solar wind aberrated terminator plane is nearly circular
Comment on 'On the response of ionospheric magnetisation to solar wind dynamic pressure from the Pioneer Venus measurements' by J. Kar and K. K. Mahajan
Recently Kar and Mahajan (1987) reanalyzed Pioneer Venus magnetometer observations that were initially published by Luhmann et al. (1980). As pointed out by Phillips (1987), by not correcting for the
Magnetic fields in the Venus ionosphere: Dependence on the IMF direction—Venus express observations
The structure of the magnetized ionosphere of Venus is investigated using the magnetometer and plasma (Analyzer of Space Plasmas and Energetic Atoms 4) data from the Venus Express spacecraft.
Solar zenith angle‐dependent asymmetries in Venusian bow shock location revealed by Venus Express
It has been long known that the Venusian bow shock (BS) location is asymmetric from the observations of the long‐lived Pioneer Venus Orbiter mission. The Venus Express (VEX) mission crossed BS near
The interaction of flowing plasmas with planetary ionospheres - A Titan-Venus comparison
Titan and Venus are both unmagnetized bodies enveloped by induced magnetospheres created within the flowing plasmas in which they are embedded. When Saturn's magnetosphere extends beyond the position
Spontaneous hot flow anomalies at Mars and Venus
We report the first observations of Spontaneous Hot Flow Anomalies (SHFAs) at Venus and Mars, demonstrating their existence in the foreshocks of other planets beyond Earth. Using data from the ESA
