This book attempts to survey the facts concerning the appearance of the auroral phenomena. Attention has been given to methods of height determination and other matters on which the original publications are not readily available. Early observers and theorists of the aurora classed it along with other atmospheric phenomena as a “meteor.” In common with many of his other ideas that remained unchallenged until well into the sixteenth century, Aristotle’s fourth century BC view of these events being the result of ignition of rising vapors belowthe innermost celestial sphere prevailed for some time. IT HAS long been assumed that aurorae, like stars, are present during daylight, but hidden by the high surface brightness of the sky. The brightest aurorae are discrete curtains of light created. The sequence of aurorae, observed at latitudes up to 55° between the years and was processed by methods of spectral analysis. The same methods were applied to parts of various duration of this interval. The periods predominant in the time series under investigation were determined. In all the selected parts of the interval, these periods are always located within the same frequency.

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic).. Auroras are the result of disturbances in the magnetosphere caused by solar wind. Aurora, luminous phenomenon of Earth’s upper atmosphere that occurs primarily in high latitudes of both hemispheres; auroras in the Northern Hemisphere are called aurora borealis, aurora polaris, or northern lights, and in the Southern Hemisphere aurora australis, or southern lights. A brief. Read the latest news and articles about astronomy and space science. Plus, amazing photos of the night sky and dramatic imagery of cosmic phenomena. Related to this trend is the growing interest in social processes, including the study of regularities in the variety of actual individual behavior within the social structure. Situational analysis have been proved useful in dealing with this process of optation, that is, selection by the individual in .

  Solar storms can also cause aurorae. This can change the course of the aurorae, shifting them towards the equator due to the magnetic disturbance of the Earth by the sun. 7. Aurorae found on other Planets. Just like aurorae on Earth [figure 2], other planets have their own versions. On Jupiter, the Jovian Aurora is found.

Henry had been taught three methods to describe and record periods of auroral activity: a spectrograph, an all-sky camera, and visual observations. The spectrograph is an instrument that is used to determine the exact wavelengths of light (in Angstrom units) being emitted from the aurora. Welcome Welcome to this site which is all about dowsing..
