Unfortunately, the first Full Moon of 2026 also falls on the same date as the peak of the Quadrantids. The January Full Wolf Moon falls just over seven hours after the shower\u2019s peak, with the Moon riding high in the constellations Auriga the Charioteer crossing into Gemini the Twins.<\/p>\n
The Quads have a relatively high 72 degree declination for the radiant. The stream approaches the Earth at near perpendicular, meaning that like the Geminids<\/a>, the Quads can start to pick up before local midnight. The Quadrantid meteors have a mid-range velocity versus the Earth of about 41 kilometers per second.<\/p>\n The source of the Quads is asteroid and potentially extinct comet 2003 EH1<\/a>. This enigmatic object is on a short 5.5 year orbit around the Sun. The Quadrantid meteors have been known of since the early 19th century.<\/p>\n What\u2019s in a name? The shower takes its name from a defunct 18th century constellation known as *Quadrans Muralis* or the Mural or Wall Quadrant. This is a device used for measuring star positions. Quadrans Muralis is one of many obsolete constellations<\/a> that fell to the wayside when the International Astronomical Union made its formal list of modern 88 constellations<\/a> in 1922.<\/p>\n Today, the radiant for the Quadrantids falls in the constellation Bo\u00f6tes the Herdsman. <\/p>\n The best way to beat the Moon is to observe from a site that places it behind a building or hill. Dress warm, and be sure to take a hot beverage of choice along. <\/p>\n Though it may not feel like it, we have the added event of Earth reaching perihelion<\/a> this weekend on January 3rd, at 17:16 Universal Time (UT) as we make our annual passage of 0.9833 AU (91.45 million miles or 147.17 million kilometers) from the Sun. Photograph Sol this weekend and again when we reach aphelion this summer on July 6th, and you can see the difference in apparent size: <\/p>\n<\/a> An elusive Quadrantid meteor.
