George Alcock
George Eric Deacon Alcock, MBE (28 August 1912, in Peterborough, Northamptonshire – 15 December 2000) was an English amateur astronomer. He was one of the most successful visual discoverers of novae and comets. George’s interest in astronomy was sparked by his first encounter with the solar eclipse of 8 April 1921. His interest evolved into the observation of meteors and meteor showers, resulting to him joining the British Astronomical Association on 27 March 1935. In 1953, he started his search for comets and in 1955 for novae. His technique involved memorization of the patterns of thousands of stars, so that he would visually recognize any intruder. In 1959, he discovered comet C/1959 Q1 — the first comet discovered in Britain since 1894. After five days, he discovered another, named C/1959 Q2. He discovered two more comets in 1963 ( C/1963 F1) and 1965 ( C/1965 S2). His first Nova was Delphini 1967 ( HR Delphini), which turned out to have an unusual light-curve. ...

Peterborough
Peterborough ( ) is a City status in the United Kingdom, cathedral city in the City of Peterborough district in the Ceremonial counties of England, ceremonial county of Cambridgeshire, England. The city is north of London, on the River Nene. As of the 2021 census, Peterborough had a population of 192,178, while the population of the district was 215,673. Human settlement in the area began before the Bronze Age, as can be seen at the Flag Fen archaeological site to the east of the city centre. There is evidence of Ancient Rome, Roman occupation. The History of Anglo-Saxon England, Anglo-Saxon period saw the establishment of a monastery, Medeshamstede, which later became Peterborough Cathedral. In the 19th century, the population grew rapidly after the coming of the railway. The area became known for its brickworks and engineering. After the Second World War, industrial employment fell and growth was limited until Peterborough was designated a New towns in the United Kingdom, n ...

Light-curve
In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the ''y''-axis and with time on the ''x''-axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid variables, other periodic variables, and transiting extrasolar planets; or aperiodic, like the light curve of a nova, cataclysmic variable star, supernova, microlensing event, or binary as observed during occultation events. The study of a light curve and other observations can yield considerable information about the physical process that produces such a light curve, or constrain the physical theories about it. Variable stars Graphs of the apparent magnitude of a variable star over time are commonly used to visualise and analyse their behaviour. Although the categorisation of variable star types is increasingly done fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorology
Meteorology is the scientific study of the Earth's atmosphere and short-term atmospheric phenomena (i.e. weather), with a focus on weather forecasting. It has applications in the military, aviation, energy production, transport, agriculture, construction, weather warnings and disaster management. Along with climatology, atmospheric physics and atmospheric chemistry, meteorology forms the broader field of the atmospheric sciences. The interactions between Earth's atmosphere and its oceans (notably El Niño and La Niña) are studied in the interdisciplinary field of hydrometeorology. Other interdisciplinary areas include biometeorology, space weather and planetary meteorology. Marine weather forecasting relates meteorology to maritime and coastal safety, based on atmospheric interactions with large bodies of water. Meteorologists study meteorological phenomena driven by solar radiation, Earth's rotation, ocean currents and other factors. These include everyday ...

3174 Alcock
3174 Alcock ( ''prov. designation'': ) is a carbonaceous Themistian asteroid from the outer region of the asteroid belt. It was discovered by American astronomer Edward Bowell at Lowell's U.S. Anderson Mesa Station in Flagstaff, Arizona, on 26 October 1984. The likely C-type asteroid has a rotation period of 7.1 hours and measures approximately in diameter. It was named after British amateur astronomer George Alcock (1912–2000). Orbit and classification The dark C-type asteroid is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,038 days). Its orbit has an eccentricity of 0.17 and an inclination of 2 ° with respect to the ecliptic. The first used observation was taken at Crimea–Nauchnij in 1973, when the body was identified as , extending its observation arc by 11 years prior to the official ...

Asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. Of the roughly one million known asteroids, the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU ...

Amateur Achievement Award Of Astronomical Society Of The Pacific
An amateur () is generally considered a person who pursues an avocation independent from their source of income. Amateurs and their pursuits are also described as popular, informal, self-taught, user-generated, DIY, and hobbyist. History Historically, the amateur was considered to be the ideal balance between pure intent, open mind, and the interest or passion for a subject. That ideology spanned many different fields of interest. It may have its roots in the ancient Greek philosophy of amateur athletes competing in the Olympics. The ancient Greek citizens spent most of their time in other pursuits, but competed according to their natural talents and abilities. The "gentleman amateur" was a phenomenon among the gentry of Great Britain from the 17th century until the 20th century. With the start of the Age of Reason, with people thinking more about how the world works around them, (see science in the Age of Enlightenment), things like the cabinets of curiosities, and the wri ...

Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding valuable service in a wide range of useful activities. It comprises five classes of awards across both civil and military divisions, the most senior two of which make the recipient either a Orders, decorations, and medals of the United Kingdom#Modern honours, knight if male or a dame (title), dame if female. There is also the related British Empire Medal, whose recipients are affiliated with the order, but are not members of it. The order was established on 4 June 1917 by King George V, who created the order to recognise 'such persons, male or female, as may have rendered or shall hereafter render important services to Our Empire'. Equal recognition was to be given for services rendered in the UK and overseas. Today, the majority of recipients are UK citizens, though a number of Commonwealth realms outside the UK continue to make appointments to the order. Honorary awards may be made to cit ...

Jackson-Gwilt Medal
The Jackson-Gwilt Medal is an award that has been issued by the Royal Astronomical Society (RAS) since 1897. The original criteria were for the invention, improvement, or development of astronomical instrumentation or techniques; for achievement in observational astronomy; or for achievement in research into the history of astronomy. In 2017, the history of astronomy category was removed for subsequent awards and was transferred to a new award, the Agnes Mary Clerke Medal. The frequency of the medal has varied over time. Initially, it was irregular, with gaps of between three and five years between awards. From 1968 onwards, it was awarded regularly every three years; from 2004 every two years; and since 2008 it has been awarded every year. The award is named after Hannah Jackson ''née'' Gwilt. She was a niece of Joseph Gwilt (an architect and Fellow of the RAS) and daughter of George Gwilt (another Fellow); Hannah donated the original funds for the medal. It is the second ...
