Eta Aquariids 2027
Debris from Halley's Comet — fast meteors best caught in the hour before dawn.
Viewing conditions this year
The Moon will be 0% illuminated on the peak night — excellent — dark skies. With dark skies, expect to catch a meaningful fraction of the quoted 50/hour ideal rate — find dark country sky and the Eta Aquariids should deliver.
What causes a meteor shower?
Comets (and a few asteroids) shed streams of dust along their orbits. When Earth crosses one of those streams — the same dates every year — the particles hit our atmosphere in parallel, appearing to radiate from one point in the sky. Each visible meteor is typically a fragment the size of a sand grain, vaporizing 80–100 km overhead.
How to actually see meteors
No telescope — your eyes have the widest field of view. Get away from city lights, give your eyes 20–30 minutes to dark-adapt (no phone screens), lie back, and watch as much sky as possible. Rates are almost always best after midnight, when your side of Earth faces into the stream. The quoted ZHR (zenithal hourly rate) is a perfect-conditions ceiling; expect to see a third to half of it under a good dark sky, less with moonlight.
Where it comes from
Eta Aquariids meteors are debris shed by 1P/Halley. They appear to radiate from the constellation Aquarius, and the shower is best seen from both hemispheres. Rates build over the active window (Apr 19 – May 28) and drop quickly after the peak.
