Epsilon Perseids meteor shower 2026

The epsilon Perseids meteor shower is expected to be active from September 5 to September 21, 2026. These meteors enter the atmosphere at speeds of approximately 64–65 km/s, with a radiant point located in the constellation Perseus. Unlike the August Perseids, the parent body for this shower has not been definitively identified, though orbital calculations suggest an undiscovered comet in a long-period, retrograde orbit.

As the shower reaches its peak during the night of September 9 to September 10, 2026, observers anticipate favorable viewing conditions. While the Rozhen National Astronomical Observatory previously suggested activity could reach approximately 8 meteors per hour, the American Meteor Society and the International Meteor Organization expect approximately one meteor per hour under ideal conditions.

Viewing conditions are aided by a new moon on September 11, which will provide minimal moonlight interference. Peak activity is anticipated around 21:00 Bulgarian time, though experts recommend optimal viewing after midnight once the Perseus constellation rises higher in the sky. Observers are advised to find locations with minimal light pollution and a wide view of the sky, noting that no telescopes or binoculars are required to see the brief, bright light trails.
