Aurora Of November 17, 1882
The Aurora of November 17, 1882 was a geomagnetic storm and associated aurora event, widely reported in the media of the time. It occurred during an extended period of strong geomagnetic activity in solar cycle 12. The event is particularly remembered in connection with an unusual phenomenon, an "auroral beam", which was observed from the Royal Observatory, Greenwich by astronomer Edward Walter Maunder and by John Rand Capron from Guildown, Surrey. Magnetic effects The magnetic storm that caused the brilliant auroral display of November 1882 was reported in ''The New York Times'' and other newspapers as having an effect on telegraph systems, which were rendered useless in some cases.The Transit of Venus storm solarstorms.org The '' |
Solar Wind
The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy between . The composition of the solar wind plasma also includes a mixture of materials found in the solar plasma: trace amounts of heavy ions and atomic nuclei such as C, N, O, Ne, Mg, Si, S, and Fe. There are also rarer traces of some other nuclei and isotopes such as P, Ti, Cr, 54Fe and 56Fe, and 58Ni, 60Ni, and 62Ni. Superposed with the solar-wind plasma is the interplanetary magnetic field. The solar wind varies in density, temperature and speed over time and over solar latitude and longitude. Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field. The boundary separating the corona from the solar wind is called the Alfvén surface. At a distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savannah Morning News
The ''Savannah Morning News'' is a daily newspaper in Savannah, Georgia. It is published by Gannett. The motto of the paper is "Light of the Coastal Empire and Lowcountry". The paper serves Savannah, its metropolitan area, and parts of South Carolina. History William Tappan Thompson, author of the ''Major Jones'' series of humorous stories, along with John McKinney Cooper as publisher and owner, founded the paper on January 15, 1850 as the ''Daily Morning News''. At the end of the Civil War in 1865, John Cooper was pardoned by President Andrew Johnson allowing him to retain ownership of the paper. Its name was changed to the ''Daily News and Herald'', though Thompson remained as editor. Thompson left the paper in 1867 to travel in Europe. In 1868, Thompson returned and the paper was renamed again to ''The Savannah Daily Morning News'' for one edition, then changed to the current name the following day. In 1870, Joel Chandler Harris, who later went on to write the Uncle Remus t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Century Magazine
''The Century Magazine'' was an illustrated monthly magazine first published in the United States in 1881 by The Century Company of New York City, which had been bought in that year by Roswell Smith and renamed by him after the Century Association. It was the successor of '' Scribner's Monthly Magazine''. It was merged into '' The Forum'' in 1930. History The initial editor was to have been Scribner's editor and co-owner Josiah G. Holland, but he died prior to the appearance of the first issue. He was succeeded by Richard Watson Gilder, the managing editor of Scribner's, who would go on to helm ''The Century'' for 28 years. Gilder largely continued the mixture of literature, history, current events, and high-quality illustrations that Holland had used at Scribner's. The magazine was very successful during the 19th century, most notably for a series of articles about the American Civil War which ran for three years during the 1880s. It included reminiscences of 230 participants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Magnetic Pole
The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the Earth's magnetic field, planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down). There is only one location where this occurs, near (but distinct from) the geographic north pole. The Geomagnetic pole, geomagnetic north pole is the northern Antipodes, antipodal pole of an ideal dipole model of the Earth's magnetic field, which is the most closely fitting model of Earth's actual magnetic field. The north magnetic pole moves over time according to magnetic changes and flux lobe Elongation (materials science), elongation in the Earth's outer core. In 2001, it was determined by the Geological Survey of Canada to lie west of Ellesmere Island in northern Canada at . It was situated at in 2005. In 2009, while still situated within the Canadian ...

Edward Israel
Edward Israel (July 1, 1859 – May 27, 1884) was an astronomer and Polar explorer. Early years Israel was born in Kalamazoo, Michigan on July 1, 1859. He was the son of Mannes and Tillie Israel, the first Jews to settle in Kalamazoo. After graduating from the Kalamazoo Public School System, Israel went to the University of Michigan, where he studied astronomy. Just before his graduation in 1881, one of Israel's professors nominated him to serve as the astronomer on an official US expedition to the Arctic. After graduation, Israel briefly returned to Kalamazoo to visit his family. Polar expedition Israel left for Washington, D.C., on April 28, 1881, to join the Lady Franklin Bay Polar Expedition with 23 other men under the leadership of Adolphus Greely.

Lady Franklin Bay Expedition
* The Lady Franklin Bay Expedition of 1881–1884 to Lady Franklin Bay on Ellesmere Island in the Canadian Arctic was led by Lieutenant Adolphus Greely, and was promoted by the United States Army Signal Corps. Its purpose was to establish a meteorological-observation station as part of the First International Polar Year, and to collect astronomical and magnetic data. During the expedition, two members of the crew reached a new Farthest North record, but of the original twenty-five men, only seven survived to return. The expedition was under the auspices of the Signal Corps at a time when the Corps' Chief Disbursements officer, Henry W. Howgate, was arrested for embezzlement. However, that did not deter the planning and execution of the voyage. Expedition First year, 1881 The Lady Franklin Bay Expedition was led by Lieutenant Adolphus W. Greely of the Fifth United States Cavalry, with astronomer Edward Israel and photographer George W. Rice among the crew of twenty-one ...

International Polar Year
The International Polar Years (IPY) are collaborative, international efforts with intensive research focus on the polar regions. Karl Weyprecht, an Austro-Hungarian naval officer, motivated the endeavor in 1875, but died before it first occurred in 1882–1883. Fifty years later (1932–1933) a second IPY took place. The International Geophysical Year was inspired by the IPY and was organized 75 years after the first IPY (1957–58). The fourth, and most recent, IPY covered two full annual cycles from March 2007 to March 2009. The First International Polar Year (1882–1883) The First International Polar Year was proposed by an Austro-Hungarian naval officer, Karl Weyprecht, in 1875 and organized by Georg Neumayer, director of the German Maritime Observatory. Rather than settling for traditional individual and national efforts, they pushed for a coordinated scientific approach to researching Arctic phenomena. Observers made coordinated geophysical measurements at multiple locatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telluric Current
A telluric current (from Latin ''tellūs'', "earth"), or Earth current, This has a detailed history of observations as understood at the time. is an electric current which moves underground or through the sea. Telluric currents result from both natural causes and human activity, and the discrete currents interact in a complex pattern. The currents are extremely low frequency and travel over large areas at or near the surface of the Earth. Description Telluric currents are phenomena observed in the Earth's crust and mantle. In September 1862, an experiment to specifically address Earth currents was carried out in the Munich Alps (Lamont, 1862). Including minor processes, there are at least 32 different mechanisms which cause telluric currents. The strongest are primarily geomagnetically induced currents, which are induced by changes in the outer part of the Earth's magnetic field, which are usually caused by interactions between the solar wind and the magnetosphere or solar radiat ...
