Alpha Capricornids and Southern Delta Aquariids peak amid full moon challenges

The Alpha Capricornids and Southern Delta Aquariids meteor showers are expected to peak this week, while the Perseids also remain active, reaching a maximum on Wednesday night. Observers in the Southern Hemisphere may have an advantage because the radiant points are higher in the sky, according to Bill Cooke, head of NASA’s Meteoroid Environment Office.

Bob Lunsford, report coordinator for the American Meteor Society, advises stargazers to seek a high-elevation site and face northward with the moon behind them to minimize moonlight interference. The Southern Delta Aquariids, originating from the Aquarius constellation, typically produce two to three meteors per hour, while the Alpha Capricornids, radiating from Capricornus, generate about three meteors per hour and are noted for brighter fireballs.

Both experts note that systematic observation of meteor showers helps scientists identify the composition and trajectories of space particles, which can improve safety assessments for human spaceflight.

The American Meteor Society lists additional peak dates for 2026, including the Perseids (August 12-13), Orionids (October 21-22), Southern and Northern Taurids (early November), Leonids (mid-November), Geminids (mid-December) and Ursids (late December).
