Minoru Honda
was a Japanese astronomer. Starting in 1937, Honda worked for Issei Yamamoto at the Zodiacal Light Observatory in Hiroshima. He discovered twelve comets between 1940 and 1968, including the periodic comet 45P/Honda–Mrkos–Pajdušáková. He discovered on FH Serpentis (Nova Serpentis 1970) on February 13, 1970 from Kurashiki, Japan. He was the first to report the very bright V1500 Cygni __NOTOC__ V1500 Cygni or Nova Cygni 1975 was a bright nova occurring in 1975 in the constellation Cygnus. It had the second highest intrinsic brightness of any nova of the 20th century, exceeded only by CP Puppis in 1942. V1500 Cygni ... (Nova Cygni 1975) at magnitude 3.0 on August 29, 1975; it peaked at 2.0, and many hundreds of independent discoveries were subsequently made by others.

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Zodiacal Light Observatory
The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets are within the belt of the zodiac. In Western astrology, and formerly astronomy, the zodiac is divided into twelve signs, each occupying 30° of celestial longitude and roughly corresponding to the following star constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. These astrological signs form a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude and the Sun's position at vernal equinox as the origin of longitude. Name The English word ' derives from , the Latinized form of the Ancient Greek ( ), meaning "cycle or circle of little animals". ...

Springer Publishing
Springer Publishing Company is an American publishing company of academic journals and books, focusing on the fields of nursing, gerontology, psychology, social work, counseling, public health, and rehabilitation (neuropsychology). It was established in 1951 by Bernhard Springer, a great-grandson of Julius Springer, and is based in Midtown Manhattan, New York City. History Springer Publishing Company was founded in 1950 by Bernhard Springer, the Berlin-born great-grandson of Julius Springer, who founded Springer-Verlag (now Springer Science+Business Media). Springer Publishing's first landmark publications included ''Livestock Health Encyclopedia'' by R. Seiden and the 1952 ''Handbook of Cardiology for Nurses''. The company's books soon branched into other fields, including medicine and psychology. Nursing publications grew rapidly in number, as Modell's ''Drugs in Current Use'', a small annual paperback, sold over 150,000 copies over several editions. Solomon Garb's ''Labor ...

Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

45P/Honda–Mrkos–Pajdušáková
45P/Honda–Mrkos–Pajdušáková is a short-period comet discovered by Minoru Honda December 3, 1948. It is named after Minoru Honda, Antonín Mrkos, and Ľudmila Pajdušáková. The object revolves around the Sun on an elliptical orbit with a period of 5.25 years. The nucleus is 1.3 kilometers in diameter. On August 19 and 20, 2011, it became the fifteenth comet detected by ground radar telescope. During the 1995 perihelion passage, the comet was visible to Solar and Heliospheric Observatory (SOHO) on January 16, 1996, when the comet was around apparent magnitude 7 and 4.3° from the Sun. It is green because it emits diatomic carbon which glows green in the near vacuum of space. 2011 passage During the 2011 perihelion passage, the comet was recovered on 5 June at magnitude 21. On 8 July, the comet had a magnitude of approximately 18, and, as of 22 July, nuclear condensation was noticed around magnitude 16. It was expected to reach a peak magnitude of around 7.3 in late ...

FH Serpentis
FH Serpentis (Nova Serpentis 1970) was a nova, which appeared in the constellation Serpens in 1970. It reached magnitude 4.4. It was discovered on February 13, 1970 by Minoru Honda located at Kurashiki, Japan. Other astronomers later studied this nova, and calculated its distances based on the decay time of its light curves. Nova Serpentis was also observed by the NASA space observatory OAO-2 Stargazer, active from 1968 to 1973. The nova was important for science because it was one of the first to be observed in multiple wavelength bands including, infrared, visible, ultra-violet, and radio. One of the observations that stood out was that it became brightest in the infrared 100 days after it was first discovered.

V1500 Cygni
__NOTOC__ V1500 Cygni or Nova Cygni 1975 was a bright nova occurring in 1975 in the constellation Cygnus. It had the second highest intrinsic brightness of any nova of the 20th century, exceeded only by CP Puppis in 1942. V1500 Cygni was discovered shining at an apparent brightness of magnitude 3.0 by Minoru Honda of Kurashiki, Japan on 29 August 1975. It had brightened to magnitude 1.7 on the next day, and then rapidly faded. It remained visible to the naked eye for about a week, and 680 days after reaching maximum the star had dimmed by 12.5 magnitudes. It is an AM Herculis type star, consisting of a red dwarf secondary depositing a stream of material onto a highly magnetized white dwarf primary. The distance of the V1500 Cygni was calculated in 1977 by the McDonald Observatory at 1.95 kiloparsecs (6,360 light years). Additionally, V1500 Cyg was the first asynchronous polar to be discovered. This distinction refers to the fact that the white dwarf's spin period ...

11442 Seijin-Sanso
Year 1144 ( MCXLIV) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar. Events By place Levant * Autumn – Imad al-Din Zengi, Seljuk governor (''atabeg'') of Mosul, attacks the Artuqid forces led by Kara Arslan – who has made an alliance with Joscelin II, count of Edessa. In support of the alliance Joscelin marches out of Edessa with a Crusader army down to the Euphrates River, to cut off Zengi's communications with Aleppo. Zengi is informed by Muslim observers at Harran of Joscelin's movements. He sends a detachment to ambush the Crusaders and reaches Edessa with his main army in late November. * December 24 – Siege of Edessa: Seljuk forces led by Imad al-Din Zengi conquer the fortress city of Edessa after a four-week siege. Thousands of inhabitants are massacred – only the Muslims are spared. The women and children are sold into slavery. Lacking the forces to take on Zengi, Joscelin II retires to his fort ...
