The Quadrantids — a top-tier shower with a catch

On the night of January 3–4, 2027, the year's first major meteor shower peaks at up to ~120 meteors an hour — rates that rival the Geminids. The catch: the maximum lasts only about six hours, not days, so the Quadrantids reward the observers whose pre-dawn window happens to line up. 2027 helps where it can — the Moon is a thin waning crescent, so the sky stays dark.

1The shower named for a constellation that doesn't exist

The Quadrantids radiate from a patch of sky that belonged to Quadrans Muralis — a constellation dropped from the official list when astronomy standardized its star maps in 1922. The shower kept the name; the sky kept the meteors. Today the radiant sits in northern Boötes, near the handle of the Big Dipper.

Like the Geminids, the Quadrantids have a rocky parent rather than a classic comet: asteroid 2003 EH₁, thought to be an extinct comet fragment — possibly the remnant of a comet observed by East Asian astronomers in 1490. Two of the year's three strongest showers come from dead or dormant comets, and nobody fully understands how either keeps its debris stream stocked.

2How to watch

• When: after midnight into the pre-dawn hours of January 4, when the radiant climbs high in the northeast. The radiant sits so far north that this is a Northern Hemisphere shower — southern observers mostly miss it.
• The timing caveat, honestly: the six-hour maximum lands at one specific stretch of Universal Time, which favors some longitudes and not others in any given year. Go out during the pre-dawn hours and you'll catch good activity either way; whether you catch the maximum is partly luck of geography.
• Conditions: this is deep winter — dress for an hour of lying still in January cold, get away from city lights, and give your eyes 20 to 30 minutes to adapt. A phone screen resets that.
• What you'll see: medium-speed meteors (~41 km/s) with a reputation for bright fireballs, radiating from near the Big Dipper's handle but streaking anywhere in the sky.

• Parent body 2003 EH₁ (identified 2003, Peter Jenniskens): a likely extinct comet fragment, possibly linked to comet C/1490 Y1 in East Asian records.
• 2027 Moon conditions computed from the lunar cycle (new Moon ~Jan 6–7, 2027): a ~10%-lit waning crescent on the peak night.
