Topline
The Perseid meteor shower — one of 2026’s celestial highlights — may be stealing the headlines this summer, but skywatchers have another opportunity to look up this week. Two annual meteor showers — the Southern Delta Aquariids and Alpha Capricornids — both peak overnight on Thursday, July 30, offering the chance to spot “shooting stars” and brilliant fireballs while the Perseids continue building toward their spectacular peak overnight on Aug. 12-13.
Key Facts
The Southern Delta Aquariids and Alpha Capricornids both peak overnight on July 30-31, according to the American Meteor Society.
The Southern Delta Aquariids can produce up to 25 meteors per hour under ideal dark skies, particularly from southern latitudes. The Alpha Capricornids are much weaker, typically producing only about five meteors per hour, but they are famous for exceptionally bright, slow-moving fireballs.
A 98%-illuminated near-full Buck Moon will dominate the sky just two days after full moon, washing out many fainter meteors, though brighter meteors should still be visible.
Meanwhile, the Perseid meteor shower is already active and will continue strengthening toward its moonless peak on Aug. 12-13.
Two Meteor Showers, Two Different Experiences
Although they peak on the same night, these showers offer very different displays. The Southern Delta Aquariids are known for producing a steady stream of relatively faint, medium-speed meteors. Observers in the Southern Hemisphere and tropical latitudes generally enjoy the best views because the radiant — the constellation Aquarius — climbs much higher in the sky. Farther north, Aquarius remains low above the southern horizon, reducing the number of visible meteors. The Alpha Capricornids are almost the opposite. They rarely produce many meteors, but those they do generate can be spectacular. The shower has earned a reputation for bright fireballs that move noticeably more slowly across the sky than the fast-moving Perseids. Their radiant point is the faint constellation Capricorn.
The Moon Will Steal The Show
This year’s biggest obstacle won’t be clouds, but moonlight. The Buck Moon reached full phase just two days earlier, leaving the sky flooded with natural light during the peak. That brightness will overwhelm many of the faint Delta Aquariid meteors, leaving only the brightest examples visible. The Alpha Capricornids may fare a little better because of their tendency to produce brilliant fireballs capable of shining through the moonlight. If you do venture outside, try to position yourself so that a tree, building or hill blocks the moon from your direct view. It won’t eliminate the glare, but it can improve your chances of spotting brighter meteors. Another tactic is to turn your back to the moon.
The Perseid Meteor Shower Builds To A Peak
The real story for many skywatchers is what comes next after the peaks of these two minor meteor showers. The Perseid meteor shower, active since July 17, continues to strengthen each night as Earth moves deeper into the debris stream left behind by Comet 109P/Swift-Tuttle, which was last in the inner solar system in 1992 and is due back in 2125, according to NASA. Even during the Delta Aquariid and Alpha Capricornid peak, you may catch the occasional Perseid streaking across the sky. While only a handful appear each hour before the shower reaches maximum activity, early Perseids are known for producing vivid green fireballs and long-lasting glowing trails. Unlike this week’s moonlit display, the Perseids will peak beneath a new moon — and on the day of a total solar eclipse — creating nearly ideal viewing conditions. Under dark skies, observers could see between 30 and 100 meteors per hour, depending on the sky’s darkness.
When And Where To Watch
For both showers, plus the Perseid meteor shower, the best time to look is after midnight and through the hours before dawn, when Earth’s rotation turns your location into the direction of incoming meteoroids. It’s also when the night sky is darkest where you are. Avoid the temptation to reach for binoculars or a telescope, which will hugely restrict your view — all you need are your own eyes. Simply find a safe location away from city lights, give your eyes at least 20 minutes to adapt to the darkness and look across the sky rather than directly at the radiant. The longest and most dramatic meteors are often seen well away from the constellation from which a shower takes its name.
