Frequently asked

When do the Eta Aquariids peak in 2027?

The Eta Aquariids reach maximum activity on the night of Wed, May 5, 2027 (computed from the shower's solar-longitude peak, the method the International Meteor Organization uses). The shower is active from Mon, Apr 19 to Sat, May 29.

How many meteors will I actually see?

The often-quoted ZHR of 50 is a theoretical ceiling (perfectly dark sky, radiant overhead). Real counts depend on your sky: from a dark-sky site expect a meaningful fraction of that; from a suburb, far fewer. Meteorcast computes the expected visible rate for your exact spot and night.

What about the moon during the 2027 peak?

The moon is 0% illuminated on the peak night — nearly moonless — excellent conditions for faint meteors.

Where should I watch from?

Somewhere dark, with an open sky and clear weather. Use the live map to compare cloud forecast, air transparency, and light pollution anywhere in North America, and to find ranked dark-sky sites near you.
