The comet reached minimum elongation on 13 March, on 25°. [4] It reached its peak brightness in April. Jacobson spotted the comet with naked eye on April 18. David H. Levy reported that the comet had an apparent magnitude of 4.7 with the naked eye on April 24. In the end of April the tail of the comet was reported to be up to 2–3 degrees long.
This unique spiral galaxy, which is situated 3.2 billion light-years from the Earth, has an extended stream of bright blue knots and diffuse wisps of young stars. [2] It rushes at 3.6 million km/h (1000km/s [2]) through the cluster Abell 2667 and therefore, like a comet, shows a tail, with a length of 600,000 light-years.
In an attempt to link the 1843 and 1880 comets to the comet in 1106 and 371 BC, Kreutz measured the fragments of the 1882 comet and determined that it was likely a fragment of the 1106 comet. He then designated that all sungrazing comets with similar orbital characteristics as these few comets would be part of the Kreutz Group. [4]
The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek.
Soon after the first orbital elements could be calculated, it was suggested that the comet would become "a bright object, that could be observed with unaided eye."It was found to combine three favorable characteristics that made it an exceptional comet for observation: a short perihelion distance, a short distance from Earth, and high intrinsic brightness. [9]
Comet Tucker, formally designated as C/2004 Q1, is a faint non-periodic comet that had a very distant perihelion on 11 December 2004. It was the second of two comets discovered by famed amateur astronomer, Roy A. Tucker .
The website, available in English and German, featured a calendar (and/or email notifications) generated for your location including information on aurora, comets, tides, solar and lunar eclipses, planets, bright satellite passes (ISS, HST, etc.), occultations, transits, iridium flares, and decaying satellites that may be visible.
The comet was favorably located in the sky to be observed by the International Ultraviolet Explorer. Comet Bradfield was the third comet whose ultraviolet spectrum was obtained from space after comets C/1975 V1 (West) and C/1978 T1 (Seargent). The observations started on 10 January 1980, when the comet was at an heliocentric distance of 0.71 AU ...
