Comet LINEAR (C/2000WM1 LINEAR)

  This is a comet discovered by Lincoln Laboratory Near Earth Asteroid Research (LINEAR) on Nov 16, 2000.
  2000WM1 LINEAR was far in the distance of about 5 AU when discovered, and its brightness reached 5th magnitude after a whole year. We could observe the comet moving down toward south sky in autumnal constellations from Nov to Dec of 2001.

Comet LINEAR (C/2001A2 LINEAR)

  This is a comet discovered by Lincoln Laboratory Near Earth Asteroid Research (LINEAR) on Jan 15, 2001.
  The comet occurred several out-bursts and brightened dramatically, had about 3.3th magnitude in middle of June in southern hemisphere. And the comet came in view fields of observers living at northern hemisphere after the end of June. We could observe it in eastern skies of dawn as a naked eye comet after long interval.

Comet LINEAR (C/1999S4 LINEAR)

   The comet was discovered by the automated LINEAR (Lincoln Laboratory Near Earth Asteroid Research) minor-planet survey team on Sep 27,1999. The team has discovered and/or detected many comets and they have same names of "LINEAR", we have to take an attention without confusing those each other.
   The comet 1999S4 LINEAR was expected that we can enjoy it as a most entertaining celestial show during summer nights of year 2000. But unfortunately it's running a little fainter than we conservatively predicted, the comet was about 6th magnitude or so even when it enters its brightest two weeks in July.

Comet Lee (C/1999H1 Lee)

This comet was discovered by an amateur astronomer Steven Lee, Australia, on Apr 16, 1999. He found the comet with 9th magnitude. Comet Lee became to be observed at Northern hemisphere from early in May onward. The comet has a magnitude of 7 in the end of May to June, visible with portable binoculars after a long separation since comet Hale-Bopp.

Comet Tempel-Tuttle (55P/Tempel-Tuttle)

A periodic comet of Tempel-Tuttle is known as an origin of Leonids shower that can be observed in medium of every November. And the meteor shower shows us the extraordinary appearance about every 33 years synchronizing with the revolutional period of the comet.

Comet Hale-Bopp (C/1995O1 Hale-Bopp)

This comet was discovered on July 22nd 1995 by two American amateuer comet-seekers, Mr. Alan Hale, New Mexico, and Mr. Thomas Bopp, Arizona. At that time, Comet Hale-Bopp was in constellation of Sagittarius, magnitude 10.5. And astronomers were surprised that the distance to this comet was over one billion kilometers(625 million miles), outer than the Jupitar's orbit. They paid much attention to this comet as "One of the greatest Comets in this Century". Comet Hale-Bopp became brighter than magnitude 0 in March 1997, and we were fascinated with splendid view of this great comet.

Comet Tabur (C/1996Q1 Tabur)

Mr. V. Tabur, Australia, discovered this comet on August 19th 1996. Comet Tabur was in the Eridanus, magnitude 10 when that was found out, and came near to us about 60 million kilometers (38 million miles) in October 1996. We could observe this comet with magnitude about 4 to 5 at that time.

Comet Hyakutake (C/1996B2 Hyakutake)

On January 30th 1996, Mr. Yuuji Hyakutake, Kagoshima pref., Japan, discovered this comet that had one of the longest tails in this century. Angular length of the ion tail of this comet was more than 100 degree, and brightness of coma was nearly magnitude 0 in March 1996.

Comet Levy (1990c=C/1990K1 Levy)

This comet was discovered by Mr. D.H.Levy, Arizona, on May 20th 1990. Comet Levy decorated the Summer Night Sky in that year with magnitude about 3.

Comet Austin (1989c1=C/1989X1 Austin)

Mr R.R.D.Austin, New Zealand, found out this comet on December 6th 1989. Astronomers predicted that comet Austin would be bright magnitude about 2 in the spring 1990. But this comet wasn't brighter than magnitude 3, and a long tail was invisible. This comet is the most famous one that disappointed us.

Comet Aarseth-Brewington (1989a1=C/1989W1 Aarseth-Brewington)

This comet was discovered on November 16th 1989 by two comet-seekers, Mr. K.Aarseth, Norway, and Mr. H.J.Brewington, South Carolia, U.S. We could see this comet in the dawn light at the end of that year.
