  • A descriptive model of F layer high‐latitude irregularities as shown by scintillation observations
    Aarons Jules (1973-11-01)
    Observations in the northern hemisphere of the amplitude fluctuations of radio signals from satellites and radio stars being used as a data base, a model is sketched of the high‐latitude F layer irregularity region. On the ...
  • A study of auroral echoes at 19.4 megacycles per second
    Malik Chester; Aarons Jules (1964-07-01)
    A study of observations of auroral returns at 19.4 Mc/s made with a low‐powered transmitter from a geomagnetic latitude of 54°N (dip angle 73°) over a period of three years has quite consistently indicated the presence of ...
  • Audio‐frequency electromagnetic radiation in the auroral zone
    Gustafsson Georg; Egeland Alv; Aarons Jules (1960-09)
    During three one‐month periods, continuous spectograms of the electromagnetic energy in the spectral region between 10 cps and 10 kc/sec were recorded in Kiruna, Sweden.The records were examined from the viewpoint of ...
  • Auroral zone emissions centered at 700 cycles per second
    Egeland Alv; Gustaffson Georg; Olsen Sven; Aarons Jules; Barron William (1965-03-01)
    An emission band between 500 and 1000 cps has frequently been recorded at the Kiruna Geophysical Observatory (geomagnetic latitude 65.3°N) by a swept frequency battery‐operated analyzer. The most important characteristics ...
  • Field‐aligned ionospheric E‐region irregularities and sporadic E
    Basu Sunanda; Vesprini Robert L.; Aarons Jules (1973-03)
    A continuous series of oblique backscatter observations at 19 MHz made at Plum Island, Massachusetts (56°N invariant), over nearly half a solar cycle is utilized to derive the occurrence characteristics of aspect‐sensitive ...
  • F layer scintillations and the aurora
    Martin Eileen; Aarons Jules (1977-07-01)
    Defense Meteorological Satellite Program photographs of the aurora are correlated with the scintillation of radio signals from both low‐altitude and synchronous satellites. Measurements from several stations ranging from ...
  • Frequency dependence of radio star scintillations
    Aarons Jules; Allen Richard S.; Elkins Terence J. (1967-06-01)
    The amplitude scintillations of the radio flux from Cygnus and Cassiopeia have been studied at discrete frequencies in the VHF‐UHF range (30, 63, 113, 228, and 400 Mhz) using a 150‐foot and an 84‐foot diameter steerable ...
  • High‐latitude irregularities during the magnetic storm of October 31 to November 1, 1972
    Aarons Jules (1976-02-01)
    By using the scintillation of satellite radio beacons and radio stars as the means of determining the intensity of F layer irregularities, observations of the high‐latitude irregularity region were made during the magnetic ...
  • Low frequency electromagnetic radiation 10–900 cycles per second
    Aarons Jules (1956-12)
    During the period of July 10 to September 15, 1955, detection of electromagnetic signals in the frequency range 10 to 900 cycles per second was undertaken. Loops and a vertical antenna were used in a site remote from ...
