When are the meteor showers in 2027?

The best-placed of the big three showers in 2027 is the Quadrantids: they peak on the night of January 3 to 4 with the moon 12% lit. The Perseids peak on the night of August 12 to 13 under a 87% moon that sets around 01:30 at 40° N, which leaves about 2 h of dark sky before dawn. The Geminids peak on December 14 at full moon, and the Lyrids, Orionids and Leonids also fall in strong moonlight. South of the equator the Eta Aquariids (new moon) and the Southern Delta Aquariids (9% moon) have the darkest peak nights.

Peaks from the International Meteor Organization's 2027 calendar. Moon, darkness and radiant heights are calculated for three latitudes; they are geometry, not a weather forecast.

The ten major showers of 2027, night by night

For each peak night at 50° N, 40° N and 35° S. Times are local solar time (on daylight saving time, add about an hour). Meteor counts are for the best moment, under a Bortle 3 and a Bortle 7 sky.

Quadrantids: night of January 3 to 4

Active December 28 to January 12 · ZHR 80 · 41 km/s · radiant in Boötes · moon 12% lit, waning

The peak rate varies from year to year, from about 60 to 200. The peak is short: rates are high for only a few hours.

Eta Aquariids: night of May 5 to 6

Active April 19 to May 28 · ZHR 50 · 66 km/s · radiant in Aquarius · new moon

The radiant rises only a few hours before dawn, so the shower is seen in the last dark hours. The peak is broad: the nights before and after give similar rates.

Rates stay near the peak for about two days.

In 2027 the Earth passes a part of the stream that Jupiter has pulled closer, which may lift the rate by 10 to 20 percent (Maslov).

How many meteors does a dark sky add?

A meteor shower's rate depends on how faint a star you can see. In a Bortle 7 suburb, the faintest stars are about magnitude 5.0; under a Bortle 3 sky, 6.5 or fainter. Each magnitude lost cuts the count by the shower's population index r (2.1 to 2.8 for these showers), so the 1.5 magnitudes between the two skies cost 3.3 times fewer Perseids (r 2.2) and 4.2 times fewer Geminids (r 2.6). Moonlight works the same way: a bright moon turns a dark site into a suburb for as long as it is up.

The rate also falls with the radiant's height: at 10° up it is 17% of the overhead rate, at 30° half, at 60° 87%. That is why the Eta Aquariids give about 33 an hour at 35° S and about 13 at 40° N on the same night.

Where to find a dark sky for the 2027 showers

Every place page on Yozora Atlas shows how dark its sky is and the darkest spots within 150 km you can drive to. Use Near me on the home page for the nearest places, or the parks list filtered to Bortle 1 to 3. The Bortle scale page explains the classes.

How the 2027 shower numbers are calculated

Peak dates and times, ZHR, radiant positions, speeds and population index come from the IMO 2027 Meteor Shower Calendar, edited by Jürgen Rendtel. Where it gives a date without an hour (Southern Delta Aquariids, Orionids), the peak night is the night before that date. The moon's phase is its share of the disc lit at the peak moment. For each latitude the night is stepped through in 10-minute steps at the Greenwich meridian: full darkness means the sun 18° or more below the horizon, the moon counts as up when its center is above the horizon, and the best moment is the radiant's highest point while it is dark and the moon down. The meteors an hour are the ZHR times the sine of the radiant's height, divided by r for every magnitude the sky falls short of 6.5. They assume a clear sky, one observer and an open view in every direction; most people count fewer.
