Double Meteor Showers to Peak in Late July, Offering Rare Skywatching Opportunity

Skywatchers will have the chance to observe two meteor showers peaking at the same time in the early hours of July 30, as the Southern Delta Aquariid and Alpha Capricornid showers reach their maximum activity. Both showers have been active since mid-July, but their simultaneous peak is considered a relatively rare event.

According to Nick Moskovitz, a planetary astronomer at Lowell Observatory, the combined showers could produce between 20 and 30 meteors per hour. The Southern Delta Aquariid shower, which originates from the constellation Aquarius and is linked to comet 96P Machholz, is best viewed from the Southern Hemisphere but will be visible in other regions as well. Its peak is expected late on July 29 through the early morning of July 30, with activity continuing until August 12.

The Alpha Capricornid shower, while generally less active with only a few meteors per hour, is known for generating bright, slow-moving fireballs. This shower has also been active since July 12 and will remain visible until August 12.

NASA advises that no special equipment is needed to view the meteor showers, but recommends finding a location away from city lights and allowing eyes to adjust to the dark for optimal viewing. "In less than 30 minutes in the dark, your eyes will adapt and you will begin to see meteors," NASA states. The best viewing time is after midnight, and observers in North America are encouraged to look toward the southern sky for the best chance to see the Southern Delta Aquariids. With the moon in a Waxing Crescent Phase and only about 25% full, visibility should be favorable for this event.
