Die '''Quadrantides''' is ’n [[meteoorreën]] wat elke jaar in [[Januarie]] te sien is. Die maksimum komete wat waargeneem kan word, is soms net so baie as dié van twee aktiewe reëns, die [[Perseïdes]] in Augustus en die [[Geminides]] in Desember,<ref name= "amsmeteors.org" >{{cite web |url=http://www.amsmeteors.org/meteor-showers/meteor-faq/#7 |title=Does the published meteor rate for a shower really represent what I should expect to see? |publisher=American Meteor Society |access-date=29 Desember 2012 |language=en |archive-url=https://web.archive.org/web/20200514112338/https://www.amsmeteors.org/meteor-showers/meteor-faq/ |archive-date=14 Mei 2020 |url-status=live |df=dmy-all}}</ref> maar Quadrantide-meteore word minder dikwels gesien omdat die hoogtepunt kort duur – soms net ’n paar uur.

== Algemene inligting ==
Die meteore oorskry die helfte van hul maksimum getal vir net agt uur (in vergelyking met twee dae by die Perseïdes). Dit beteken die stroom stofdeeltjies wat die Quadrantides veroorsaak, is besonder smal.<ref name= "space.com" /> Die moederliggaam van die meteoorreën is tentatief in 2003 deur Peter Jenniskens<ref name= "sjaa" /> geïdentifiseer as die [[kleinplaneet]] {{mp|2003 EH|1}}, wat op sy beurt kan verband hou met die [[komeet]] C/1490&nbsp;Y1,<ref name= "Jenniskens2004" /> wat sowat 500 jaar gelede deur Sjinese, Japannese en Koreaanse sterrekundiges waargeneem is.

Die [[uitstralingspunt]] van dié meteoorreën is in die [[sterrebeeld]] [[Veewagter (sterrebeeld)|Veewagter]], nie ver van die [[Groot Wa]] nie.<ref name= "space.com" >{{cite web |url=http://www.space.com/spacewatch/081219-ns-meteor-shower.html |title=Stellar Meteor Shower Januarie 3 |publisher=Space.com |access-date=3 Januarie 2009 |language=en |archive-url=https://web.archive.org/web/20110107032515/http://www.space.com/spacewatch/081219-ns-meteor-shower.html |archive-date= 7 Januarie 2011 |url-status=live |df=dmy-all }}</ref> Dit word die beste in die [[Noordelike Halfrond]] gesien, maar is ook sigbaar tot 51 grade suid.<ref name= "Meteorwatch" />

Die naam is afgelei van Quadrans Muralis, ’n voormalige sterrebeeld wat in 1795 deur die Franse sterrekundige Jérôme Lalande geskep en nou deel van die Veewagter is. Vroeg in Januarie 1825 het Antonio Brucalassi in Italië berig oor die "talle helder liggame in die lug wat bekend is as verskietende sterre".<ref name= "meteorshowersonline.com" >{{cite web |url=http://meteorshowersonline.com/quadrantids.html |title=Quadrantids |publisher=meteorshowersonline.com |access-date=29 Desember 2012 |language=en |archive-url=https://web.archive.org/web/20180325222929/http://meteorshowersonline.com/quadrantids.html |archive-date=25 Maart 2018 |url-status=dead |df=dmy-all }}</ref> Dit het gelyk of hulle uit Quadrans Muralis kom. In 1839 het Adolphe Quetelet in [[België]] en Edward C. Herrick in [[Amerika]] onafhanklik van mekaar voorgestel dat die Quadrantides ’n jaarlikse meteoorreën is.<ref name= "earthsky.org" >{{cite web |url=http://earthsky.org/astronomy-essentials/everything-you-need-to-know-quadrantid-meteor-shower |title=Everything you need to know: Quadrantid meteor shower |publisher=EarthSky |access-date=29 Desember 2012 |language=en |archive-url=https://web.archive.org/web/20200505054256/https://earthsky.org/astronomy-essentials/everything-you-need-to-know-quadrantid-meteor-shower |archive-date=5 Mei 2020 |url-status=live |df=dmy-all}}</ref>
