Mar 01, 1961 · IN accordance with the recommendations of the Special Committee on Antarctic Research the programme of auroral observation conducted during the International Geophysical Year at Halley Bay, Antarctica, was continued into 1959. The Halley Bay Base, established by the Royal Society International Geophysical Year Expedition and now administered by the Falkland Islands.
As was expected, the auroral observations were far more numerous at Halley Bay, but, nevertheless, a clear correlation between the peaks of activity there and the rarer auroral echoes at Jodrell Bank has emerged, and the scattering mechanism is also clearly specular. Download PDF: Sorry, we are unable to provide the full text but you may find it at the following locations: nora.nerc./id/epri. external link http. Visual observations made at Halley Bay, Antarctica, in the years 1956–1965 are used to study variations in the position of quiet homogeneous arcs. The diurnal variations in median latitude and mean azimuth of the highest point on the lower border of the arcs are similar from year to year. Ground observations of magnetic and ionospheric substorms are reviewed, and the processes involved are explained. Then magnetic and absorption results from an auroral zone station, Halley Bay, are examined. Positive H bays occur in the evening sector between 16.00 and 22.00 local time while negative H bays occur on the nightside between 22.00 and 06.00 local time. Clockwise and.
A statistical model of auroral echo occurrence has been made from an analysis of observations at 48.5 Mc/s obtained over a number of years of continuous operation. The probability density distribution of auroral target cross sections σ has been examined experimentally, and the resulting curve fitted by simple mathematical relations. The Babylonian auroral observation is remarkable in the sense that it is one of a series of carefully recorded astronomical observations, for each of which the year, month and day are known precisely. This observation occurred at a time when the geomagnetic dipole latitude of Babylon was about 41°N compared with the present value of 27.5°N. Auroral-E Observations: The First Year's Data R. B.

Abstract Observations of the radio aurora were made from Halley Bay, British Antarctic Territory, during the IQSY using a system of three rhombic aerials at a frequency of 71.3 MHz. Auroral Observations at Halley Bay, Antarctica, during 1959. March 1961. A detailed analysis of the results of the first three years observations has appeared elsewhere1, and it is interesting. observations, well outside the more modern range of wide observational coverage see Vaquero and Vázquez, 2009; Clette et al., 2014. Therefore, in order to infer the general trend of solar activity and the occurrence of CMEs, candidate auroral records have been sought in historical documents around these events e.g., Usoskin et al., 2013.

In the reduction of the Halley Bay data, therefore, it was decided to define an auroral zone in terms of the median position of quiet arcs. A feature of the aurorae at Halley Bay was the almost continuous presence of a quiet arc lying well to the south of the station. In the.

and Kokubun, 1960; Wescott 1961; and Westcott and Mather, 1965, magnetic records from Halley Bay and Bryd Station near the southern auroral zone are used to improve the station distribution. Locations of the points conjugate to Halley Bay and Byrd Station are also shown in Figure 2. Apr 09, 2012 · Halley Research Station, part of the British Antarctic Survey located on the Brunt Ice Shelf, was also positioned to provide opportunities for auroral observations.

Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey BAS. The base was established in 1956 to study the Earth's atmosphere.Measurements from Halley led to the discovery of the ozone hole in 1985. The current base is the sixth in a line of designs to overcome the challenges of building on a floating ice shelf where. , ‘ The southern auroral zone in Geomagnetic Longitude Sector 20E ’, Journal of Geophysical Research 1959, 64, 1381 –8; Evans, S., ‘ Horizontal movements of visual auroral features ’, Journal of Atmospheric and Terrestrial Physics 1959, 16, 190 –2; idem, ‘Systematic movements of aurorae at Halley Bay’, Proceedings of the.

There are several important differences between the RREs and the unusual VLF emissions at Halley Bay Francis et al 1983. The duration of separate RREs is much longer and amounts ~30–60 s or even more as is seen in figure 4, as opposed to tenths of a second at Halley Bay see figures 1.

before I was on the receiving end of his expositions, mostly about Halley Bay. He had a lab full of Halley Bay data from the International Geophysical Year and frequently bounced in and treated anyone within earshot, from the Director to the office cleaners, to a memorable experience. His analysis of Arctic and Antarctic ionospheric data led. Observations are for locations within the austral auroral absorption zone and on the polar cap. It is found that the parameters of a power law used to describe the calculated PDFs are consistent with the formation of coherent structures being more frequent within the auroral zone, as a manifestation of intermittency. 2015 COSPAR. Observations are for locations within the austral auroral absorption zone and on the polar cap. It is found that the parameters of a power law used to describe the calculated PDFs are consistent with the formation of coherent structures being more frequent within the auroral. Global observations of ozone on a daily basis were provided with TOMS, first flown on the Nimbus-7 mission of NASA launch Oct. 24, 1978. 2 During its lifetime on Nimbus-7, the analysis of TOMS data helped make ”ozone” a household word through its false-color images of the “Antarctic Ozone Hole.

Since 1957, when Amundsen-Scott South Pole Station was opened as one of the key stations for the International Geophysical Year IGY, the National Institute of Polar Research NIPR has. Contributions to the basic theory and methods of analysis are first dealt with. News concerning measuring technique are then briefly treated. In the main part of the paper the development of our knowledge of sudden cosmic noise absorption, polar cap absorption, and auroral absorption is reviewed. The emphasis is on the ionospheric effects.
The data is primarily that collected onboard the NASA ER-2 and DC-8 aircraft, along with ozonesonde data collected at four Antarctic stations: Halley Bay, McMurdo, Palmer Station, and the South Pole. The experiment tested the chemical and dynamical theories of the ozone hole using the aircraft data in theoretical computer models of the. erage of foF2 ionosonde observations is not globally uniform due to the high cost of acquiring and main Eleven order harmonic analysis of the estimated slab thickness from t=0 until 23, results to 23 coefﬁ 21 Halley Bay 1957-1980 -75.5 -26.6 -66.5. James Paton was born at Cowdenbeath on 2 September 1903.His sudden death on 26 August 1973, on the eve of his retirement, was a great shock to his family and will be deeply regretted in the wide circle of his friends and professional colleagues. With parents who were fond of music, and with four lively younger brothers, his early days in the family home at Ackergill, Kelty, were happy ones.

Greenwald This project involves the operation and maintenance of radar at Goose Bay, Labrador, Canada.
Recent observations from the new perspective of the POLAR orbit have elucidated the crucial role that parallel electric fields and the ionosphere play in the development of a magnetic storm. During the main phase, we observed field-aligned beams of ionospheric ions that appear to be caused by deeply convecting plasmasheet ions. Planet. Space Sci. 1969, Vol. 17, pp.421 to 431. Permmm Pen.
