Leslie C. Peltier
Leslie Copus Peltier (January 2, 1900 – May 10, 1980) was an American amateur astronomer and discoverer of several comets and novae, including Nova Herculis 1963. He was once described as "the world's greatest non-professional astronomer" by Harlow Shapley. Biography Leslie Copus Peltier was born in Delphos, Ohio. Delphos is located in northwestern Ohio in both Van Wert and Allen County. His homeplace was located on South Bredeick Street, and his home is still standing today. The home was known as Brookehaven. Peltier married Dorothy Nihiser in November 1933. An amateur astronomer, he was a prolific discoverer of comets and also a persistent observer of variable stars and member of the AAVSO. He was co-discoverer of 12 comets, 10 of which carry his name, and over a span of more than 60 years made more than 132,000 variable star observations.

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

3850 Peltier
3850 Peltier, provisional designation , is a Florian asteroid and suspected interloper from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 7 October 1986, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station, near Flagstaff, Arizona. The asteroid was named after American amateur astronomer Leslie Peltier. Orbit and classification In the SMASS taxonomy, ''Peltier'' is a V-type asteroid but possesses the orbital characteristics of a member of the Flora family, which is one of the largest groups of stony S-type asteroids in the main-belt. It is therefore thought to be an unrelated interloper that does not origin from the Flora family's parent body. ''Peltier'' orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,220 days). Its orbit has an eccentricity of 0.16 and an inclination of 5 ° with respect to the ecliptic. In 1949, it was first identified as a ...

Discoverers Of Comets
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collabo ...

Amateur Astronomers
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1980 Deaths
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 '' Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Light Pollution
Light pollution is the presence of unwanted, inappropriate, or excessive use of artificial Visible spectrum, lighting. In a descriptive sense, the term ''light pollution'' refers to the effects of any poorly implemented lighting, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind of pollution, but also as a contributor to the wider, collective impact of various sources of pollution. Although this type of pollution can exist throughout the day, its effects are magnified during the night with the contrast of darkness. It has been estimated that 83 percent of the world's people live under light-polluted skies and that 23 percent of the world's land area is affected by skyglow. The area affected by artificial illumination continues to increase. A major side-effect of urbanization, light pollution is blamed for compromising health, disrupting ecosystems, and spoiling aesthetic environments. Globally, it has incr ...

Delphos, Ohio
Delphos is a city in Allen and Van Wert counties in the U.S. state of Ohio approximately 14 mi (23 km) northwest of Lima and 13 mi (21 km) east of Van Wert. The population was 7,101 at the 2010 census. The Allen County portion of Delphos is part of the Lima Metropolitan Statistical Area, while the Van Wert County portion is part of the Van Wert Micropolitan Statistical Area. History Delphos had its start in the early 1850s with the merger of neighboring rival towns. These were the towns of Howard (in the northwest), Section 10 (in the east), Bredeick Street (south of Howard) and East Bredeick (named after Father John Otto Bredeick, a Bavarian priest, who had purchased the tract of land in 1840). In 1851, the four towns agreed to form a single town called Delphos. The city's name is derived from the Greek god Delphus. The Miami and Erie Canal, a 274 mile (441 km) canal connecting Cincinnati to Toledo, ran through Delphos. The first settlers to Delphos ...

AAVSO
The American Association of Variable Star Observers (AAVSO) is an international nonprofit organization, founded in 1911, focused on coordinating, analyzing, publishing, and archiving variable star observations made largely by amateur astronomers. The AAVSO creates records that establish light curves depicting the variation in brightness of a star over time, and makes them available to professional astronomers, researchers, and educators. Since professional astronomers do not have the time or the resources to monitor every variable star, astronomy is one of the few sciences where amateurs can make genuine contributions to scientific research. During 2011, the 100th year of the AAVSO's existence, the 20-millionth variable star observation was received into the database. The AAVSO International Database (AID) stores over 35 million observations as of 2019. The organization receives nearly 1,000,000 observations annually from around 2,000 professional and amateur observers and is quot ...
