    Notes: [Auszug] WHAT do long term experiments in Antarctica have in common with experiments on scientific satellites? One obvious answer is their remoteness. And in what way do they differ? Data from satellites are available in real time and can even be analysed directly by dedicated computers on the ground, ...

    Notes: [Auszug] It is believed that the terrestrial analogue of the saturnian narrowband electromagnetic emissions is terrestrial myriametric radiation (TMR), also known in the past as non-thermal continuum. To standardize the nomenclature, the narrow-band electromagnetic emissions observed at Saturn will be ...

    Notes: [Auszug] Observations by the Dynamics Explorer 1 satellite provide validation of the theory that terrestrial myriametric radiation is produced by the linear conversion of electrostatic upper hybrid waves to electromagnetic radiation via a radio window. This theory predicts that the myriametric radiation is ...

    Notes: [Auszug] Voyager 1 (VI) approached Jupiter at 10:30 local time (LT) at jovicentric latitude 3.2°. Jupiter's magnetic axis is tilted 9.6° from its rotation axis, the north magnetic pole being at 202° central meridian longitude (CML). Therefore when VI approached Jupiter, its magnetic latitude varied ...

    Notes: [Auszug] bKOM first appeared in the planetary radio astronomy (PRA) data when Voyagers were 〉2AU from the planet1'2. Figure 1 shows a PRA wave spectrogram5 in which bKOM is the tapered emission recorded when Jupiter's north magnetic pole (located at central meridian longitude, CML = 202) is tilted towards ...

    Notes: [Auszug] Trapped non-thermal continuum (NTC) is used to describe broad-band radio noise at frequencies ^40 kHz observed by spacecraft in the plasmatrough, the cavity of low-density plasma between the Earth's plasmasphere and magnetosheath1. Escaping NTC is noise at higher frequencies which propagates ...

    Notes: [Auszug] The Voyager missions have revealed that jovian kilometric radiation (emanating from Jupiter's magnetosphere) is beamed away from the zenomagnetic equator. Results from GEOS 1 show that terrestrial non-thermal continuum or myriametric radiation is similarly beamed away from the geomagnetic ...

    Notes: [Auszug] Observations from satellites have revealed the existence of continuum radiation from just beyond the plasmapause. I propose here that this is generated by Cerenkov radiation coupling to the O mode of radiation, which can propagate in low density plasmas. The observations are interpreted on the ...

    Notes: [Auszug] It is well known from satellite observations that radio noise is produced by charged particles streaming through the mag-netosphere and ionosphere (see Mosier et al.4 and references therein). One frequency range in which particularly intense noise is observed is that lying between the plasma ...

    VLF electromagnetic waves observed onboard GEOS-1 (1978)
    Springer
    Space science reviews 22 (1978), S. 371-382 
    Details
    ISSN: 1572-9672
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract This paper is concerned mainly with the information which can be extracted from frequency-time spectra in the VLF range. The instrument used is the correlator which has a good frequency resolution (50 Hz) and time resolution (30 ms) in one magnetic and one electric component simultaneously. By suitable computer analysis, it is possible for instance to distinguish between the two dominant electromagnetic emissions, hiss and chorus, as well as to display the complete spectra. This treatment is applied to the Survey periods, which are a fixed sequence of modes, repeated every hour on the hour in order to have reference data from GEOS analogous to many ground-based observatories. One result of this treatment obtained already is that hiss and chorus normally appear together, although one or the other may be dominating in intensity. The occurrence rate of these emissions in local time is also given. For continuous surveillance the filterbank data are used. There are 16 frequency filters supplying magnetic and electric amplitude at few different frequencies. Using these data, a storm sudden commencement can be followed with good time resolution (1 s), and an interesting correlation has been found in a few cases between the VLF signal amplitude and the cold plasma density (as measured by the active part of the S-300 experiment).
