Skygazers can look forward to two meteor showers peaking back-to-back in the late evening hours of July 28 through July 31. The celestial events feature the Southern Delta Aquariids followed closely by the Alpha Capricornids.
A meteor shower occurs when Earth's orbit intersects with a cloud of debris left behind by an asteroid or comet. These remnants burn up upon entering the atmosphere, creating streaks of light and fireballs.
The Southern Delta Aquariids, active from mid-July to late August, originate from the short-period comet 96P/Macholz. This shower's radiant point is in the constellation Aquarius. Its peak viewing window is the evenings of July 28 and 29, with an estimated 15 meteors per hour. These meteors are typically faint and may have weak trails. Visibility could be affected by the waxing gibbous moon. However, the Southern Delta Aquariids have been known to produce outbursts, with notable events in 1977 and 2003.
The Alpha Capricornids, a byproduct of comet 169/NEAT, are set to peak on July 30 and 31. Their radiant point is in the constellation Capricorn. While this shower is less prolific, producing about five meteors per hour at its peak, its meteors are known for their exceptional brightness.
Both showers are best viewed under clear, dark skies, away from light pollution. Experts recommend allowing about 30 minutes for eyes to adjust to the darkness. While telescopes or binoculars can be used, observers are advised to lie back and view the entire sky. The Southern Delta Aquariids are best seen from the Southern Hemisphere or southern latitudes of the Northern Hemisphere, while the Alpha Capricornids should be visible from both hemispheres.
Viewing for both showers is recommended to begin around 10 p.m. and continue until dawn for the best chance of observation.
