sentences: Comet Donati, or Donati's Comet, formally designated C/1858 L1 and 1858 VI, is a long-period comet named after the Italian astronomer Giovanni Battista Donati who first observed it on June 2, 1858.
 After the Great Comet of 1811, it was the most brilliant comet that appeared in the 19th century.
 It was also the first comet to be photographed.
A great comet is a comet that becomes exceptionally bright.
 There is no official definition; often the term is attached to comets such as Halley's Comet, which are bright enough to be noticed by casual observers who are not looking for them, and become well known outside the astronomical community.
 Great comets are rare; on average, only one will appear in a decade.
 Although comets are officially named after their discoverers, great comets are sometimes also referred to by the year in which they appeared great, using the formulation "The Great Comet of ...", followed by the year.
X/1106 C1, also known as the Great Comet of 1106, was a great comet that appeared on 2 February 1106, and was observed across the world from the beginning of February through to mid-March.
 It was recorded by astronomers in Wales, England, Japan, Korea, China and Europe.
 It was observed to split into many pieces, forming the Great Comet of 1843, Great Comet of 1882, Comet Pereyra, Comet Ikeya–Seki and C/2011 W3 (Lovejoy), as well as over 3000 small sungrazing comets observed by the SOHO space telescope.
 It is a member of the Kreutz Group, known as Subfragment I, a split from an earlier large (~150 km) comet that progressively fragmented under influence of the Sun.
Arago was born at Estagel, a small village of 3,000 near Perpignan, in the "département " of Pyrénées-Orientales, France, where his father held the position of Treasurer of the Mint.
C/1807 R1 (also known as the Great Comet of 1807) is a long-period comet, which in 1807 was visible to naked-eye observers in the northern hemisphere from early September to late December.
 On the basis of its outstanding brightness it is called a great comet.
The Great Comet of 1861 formally designated C/1861 J1 and 1861 II, is a long-period comet that was visible to the naked eye for approximately 3 months.
 It was categorized as a Great Comet, one of the eight greatest comets of the 19th century, according to Donald Yeomans.
C/1881 K1 (also called the Great Comet of 1881, Comet Tebbutt, 1881 III, 1881b) is a long-period comet discovered by John Tebbutt on 22 May 1881 at Windsor, New South Wales.
 It is called a great comet because of its brightness at its last apparition.
The Great Comet of 1819, officially designated as C/1819 N1, also known as Comet Tralles, was an easily visible brilliant comet, approaching an apparent magnitude of 1–2, discovered July 1, 1819 by Johann Georg Tralles in Berlin, Germany.
 It was the first comet analyzed using polarimetry, by François Arago.
The Great Comet of 1843, formally designated C/1843 D1 and 1843 I, was a long-period comet which became very bright in March 1843 (it is also known as the Great March Comet).
 It was discovered on February 5, 1843 and rapidly brightened to become a great comet.
 It was a member of the Kreutz Sungrazers, a family of comets resulting from the breakup of a parent comet (X/1106 C1) into multiple fragments in about 1106.
 These comets pass extremely close to the surface of the Sun—within a few solar radii—and often become very bright as a result.
The Great Comet of 1744, whose official designation is C/1743 X1, and which is also known as Comet de Chéseaux or Comet Klinkenberg-Chéseaux, was a spectacular comet that was observed during 1743 and 1744.
 It was discovered independently in late November 1743 by Jan de Munck, in the second week of December by Dirk Klinkenberg, and, four days later, by Jean-Philippe de Chéseaux.
 It became visible with the naked eye for several months in 1744 and displayed dramatic and unusual effects in the sky.
 Its absolute magnitude — or intrinsic brightness — of 0.5 was the sixth highest in recorded history.
 Its apparent magnitude may have reached as high as -7, leading it to be classified among what are called the "Great Comets".
 This comet is noted especially for developing a 'fan' of six tails after reaching its perihelion.
