• The Geminid shower should have been visible in the night sky since Saturday.
• Look for Geminid meteors early on Dec . 14.
• WATCH FOR GEMINID METEORS THIS WEEK ( a)
• In 1864 and 1873 he observed the bright green colour of two respective Geminid meteors.
• Another suspected Palladian is 3200 Phaethon, the parent body of the Geminid meteor shower.
• Constellations nearest the radiant give the meteor showers their names, and so the Geminid shower is named for the constellation Gemini.
• The Geminid meteors occur under ideal, moonless conditions on the 13th and 14th to deliver the best shower of the year.
• Monda said, " and not too far into the next century, there will not be a Geminid meteor shower ."
• But Monda and other enthusiasts say the Geminid shower is worth the effort, all the more so because it won't make its yearly returns forever.
• But the Geminid shower probably puts on a better display, said John Delano, chair of the department of earth and atmospheric sciences at the State University at Albany.
• The annual Geminid meteor shower should reach its peak late Thursday ( cq-Dec . 13 ) or early Friday, ( cq { ndash } Dec . 14 ) astronomers say.
• The radiant for the Geminid meteors is fairly easy to find, said Denice Cross, a Guilderland resident and amateur astronomer who is a lecturer at the Schenectady Museum & Planetarium.
• The Geminid shower has been observed for about 150 years, but because the debris cloud is gradually changing position, there will come a time when its orbit no longer intersects with Earth's.
• This led to the discovery of three asteroids, including 3200 Phaethon ( an Apollo asteroid and the parent body of the Geminid meteor shower ), six comets, and a huge dust trail associated with comet 10P / Tempel.
• Shortly after its discovery, Fred Whipple observed that the " orbital elements of 1983 TB shown on IAUC 3879 are virtually coincident with the mean orbital elements of 19 Geminid meteors photographed with the super-Schmidt meteor cameras ".
• Such is the slow birth and brief life of a meteor _ a " shooting star " of the type that are expected to flash through the sky by the thousands this month as the Geminid meteor shower puts on its annual show.
• :That seems to be the Geminid shower . . . there's not much use in reporting them though, unless one happened to survive and landed in your backyard : ) Adam Bishop 17 : 44, 15 Dec 2003 ( UTC)
• The Geminid shower is expected to be especially good this year because the moon will be a crescent, only about four days past its new phase, and expected to set around 8 p . m . The moon's absence will make for even better viewing because it will mean that much less light to dull the sky, Monda said.
• IRAS has also discovered two other minor planets, the 11-kilometer sized main-belt asteroid and 3200 Phaethon, a near-Earth and potentially hazardous object, parent body of the Geminid meteor shower, as well as six comets, such as 126P / IRAS, a short-period Jupiter family comet, which was also named after the discovering space observatory.
• Some of these include shower caused by Halley's comet, ( early May's Eta Aquarid meteors and late October's Orionid meteors ), comet Swift-Tuttle, ( mid-August's Perseid meteors ), comet Giacobini-Zinner, ( early October's Draconid, or " Giacobinid " meteors ), and even one sparked by an asteroid named Phaeton, whose resulting mid-December Geminid meteors are very eye-catching indeed.
