An improved representation for evolving programs
A representation has been developed that addresses some of the issues with other Genetic Program representations while maintaining their advantages. This combines the easy reproduction of the linear representa...

Detection of langmuir solitons: implications for type III burst emission mechanisms at 2ω PE
We present the experimental verification of existing theoretical models of emission mechanisms of solar type III bursts at the second harmonic of the plasma frequency, ω pe . Thi...

The three-dimensional extent of a high speed solar wind stream
A primary goal of the Ulysses mission is to study the 3-dimensional structures making up the interplanetary medium, and example of which is the high speed solar wind stream observedin situ by Ulysses beginning in...

Ulysses/Galileo observations of type III radio bursts and associated in-situ electrons and Langmuir waves
Both the Ulysses and Galileo spacecraft detected energetic electrons and Langmuir waves that were associated with a type III radio burst on 10 December 1990. At the time of these observations, these spacecraft...

Interplanetary type III radio bursts observed simultaneously by ICE
We analyze two solar type III radio bursts that were observed simultaneously by the ICE and Ulysses spacecraft. Both bursts originated behind the solar limb as viewed from either spacecraft. At the time of the...

Interplanetary type III radio bursts observed from high southern heliographic latitudes
Type III radio bursts observed from high southern latitudes are analyzed for the first time. The continual observation of these radio bursts by Ulysses from after the Jupiter swing-by to 50°S latitude argues f...

Evidence for halo-like radio sources from kilometric type III burst observations
The radio azimuths for many kilometric type III bursts that originate near or behind the limb of the Sun are observed to drift far to the east or far to the west of the spacecraft-Sun line. It is shown that th...

Kilometric shock-associated events and microwave bursts
The peak times of impulsive microwave bursts are compared with those of shock-associated (SA) kilometric radio events. The first peaks in these two frequency regimes are usually well-correlated in time, but th...

Characteristics of solar coronal source regions producing 3He-rich particle events
We use Hα, X-ray, and kilometric radio data to examine the solar coronal activity associated with energetic (∼1 MeV/nucl−1) 3He-rich particle events observed near Earth. The basis of the study is the 12 3He-rich ...

Characteristics of shock-associated fast-drift kilometric radio bursts
The existence of a class of fast-drift, shock-associated (SA), kilometric radio bursts which occur at the time of metric type II emission and which are not entirely the kilometric continuation of metric type I...

A new method for reconstructing type III trajectories
A local density approximation (LDA) method is developed for reconstructing the trajectories of type III radio bursts through the interplanetary medium. The method uses the measured source directions and the me...

Type II solar radio events observed in the interplanetary medium
Fifteen type II solar radio events have been identified in the 2 MHz to 30 kHz frequency range by the radio astronomy experiment on the ISEE-3 satellite over the period from September 1978 to December 1979. Th...

Hectometric and kilometric solar radio emission observed from satellites in August 1972
Type II, III, and continuum solar radio events, as well as intense terrestrial magnetospheric radio emissions, were observed at low frequencies (10 MHz to 30 kHz) by the IMP-6 satellite during the period of hi...

Radio evidence for an expanding magnetic arch beyond 20 solar radii
A magnetic loop located beyond 20 R ⊙ appears to be the later evolution of an expanding magnetic arch observed at 2 r ⊙. The expansion speed is of the order of 100 km s−1.

Characteristics of type III exciters derived from low frequency radio observations
Low frequency radio observations (2.8 MHz-67 kHz) from the RAE-1 and IMP-6 satellites allow the tracking of type III solar burst exciters out to large distances from the Sun (of the order of 1 AU). A study of ...
