Overview
- The minor September shower is active from September 5 to 21, with the maximum falling around September 8–9 and the best viewing after midnight into pre-dawn.
- Near-full moonlight—about 97% illumination following the September 7 eclipse—will wash out fainter meteors and significantly reduce visibility.
- The radiant lies near the star Epsilon Persei in the constellation Perseus, and the display is observable across Mexico, including Baja California, as well as much of the Northern Hemisphere.
- The shower’s typical zenithal hourly rate is about five meteors under ideal conditions, and the fast streaks enter Earth’s atmosphere at roughly 64 km/s.
- Viewing tips include choosing rural dark-sky locations, blocking the Moon with a building or tree, avoiding telescopes or binoculars, and allowing 20–30 minutes for dark adaptation.
