Kappa Cygnid Meteor Shower 2026: Don’t Miss Shooting Stars on August 17
The Kappa Cygnid meteor shower peaks on August 17, 2026, producing up to three meteors per hour under dark skies. Although the shower is weak, it is known for occasional bright, slow-moving fireballs that can appear anywhere in the sky.
Viewing conditions will be favorable in 2026: the waxing crescent Moon will set early, leaving most of the night dark. The shower is best seen from the Northern Hemisphere, where its radiant remains above the horizon for much of the night.
Use the Sky Tonight app to plan your viewing — and read on to learn when and where to watch, what to expect, and why this subtle summer shower is worth your attention.

Kappa Cygnids 2026: When and Where to See
- Active: August 3 – 28
- Peak of activity: August 17
- Meteors/hour: 3
- Velocity: 25 km/sec (16 mi/sec)
- Moon phase: Waxing crescent

- Parent body: Uncertain
- Best visible from: Northern Hemisphere
The Kappa Cygnids (κ-Cygnids) are a low-rate meteor shower known for slow, occasionally bright meteors. Their radiant region is complex, spreading into Draco and Lyra, so meteors may appear from a broader patch of sky than a single point.
Kappa Cygnids 2026: Visibility Forecast
In 2026, viewing conditions for the Kappa Cygnids will be favorable. The shower will peak under a waxing crescent Moon, which will set early in the evening, leaving the rest of the night dark for relaxed, uninterrupted meteor watching.
Where Are the Kappa Cygnids Visible?
The radiant of the Kappa Cygnids (a point from which meteors appear to fly out) is located near the star Kappa Cygni in the constellation Cygnus. The radiant is well-positioned in the Northern Hemisphere — at latitudes north of about 35°N, the radiant is circumpolar and remains above the horizon all night. At lower northern latitudes, it is still well placed but may spend part of the night below the horizon. In the Southern Hemisphere, it remains low; south of about 35°S, it does not rise at all.
The main thing you need to know: the higher the radiant is in the sky, the more meteors you are likely to see. However, you don’t need to look directly at the radiant — the shooting stars will be visible across the entire sky, and often appear with longer trails when they are further from the radiant.
To locate the radiant and learn how high it is, use the Sky Tonight app: just search for “Kappa Cygnids” and tap the target icon next to the result.
What Is the Best Time to Watch the Kappa Cygnids?
Start watching after the Moon sets on the night of August 16–17. From mid-northern latitudes, the radiant is already well placed in the evening and remains visible throughout the night. Around 11 p.m. local time is a practical starting point, but any dark hour can produce an occasional Kappa Cygnid fireball.
How Many Kappa Cygnids Can You See per Hour?
Under dark skies, the Kappa Cygnids may produce up to three meteors per hour near the peak. The low rate is balanced by the shower’s main attraction: its meteors are unusually slow, and some become striking fireballs. Plan to watch for at least an hour, since long gaps between meteors are normal.
Also, the Kappa Cygnids experience outbursts of activity every 6–7 years, with the last such event recorded in 2021. Unfortunately, according to astronomers, no enhanced rates of meteor activity are expected in 2026.

How to See Kappa Cygnid Meteors?
Here are some tips to help you make the most of the Kappa Cygnids peak:
-
Get away from city lights. A dark, unobstructed view of the night sky is essential.
-
Keep a wide area of the sky in view. Although the meteors appear to originate near the constellation Cygnus, they can flash across any part of the sky.
-
Be patient. With only a few meteors expected per hour, it's crucial to settle in for at least an hour.
-
Allow your eyes to adjust. It takes about 20 minutes for your vision to fully adapt to darkness. Avoid looking at your phone; if you need to consult a stargazing app, turn on the Night Mode that will preserve your night vision.
-
Dress warmly. Even in August, nighttime temperatures can dip. Bring a chair, blanket, or sleeping bag, and perhaps a warm drink to stay cozy.

What Is the Kappa Cygnid Meteor Shower?
The Kappa Cygnids (κ-Cygnids) are a meteor shower with no known parent body, making them particularly interesting to astronomers. One candidate for the parent body is the asteroid 2008 ED69, but it hasn’t been confirmed yet. Certain studies also suggest that the shower’s radiant is unusually complex: it extends over a region of about 10 degrees, spanning over three constellations — Cygnus, Draco, and Lyra.
The Kappa Cygnids were first observed by the Hungarian astronomer Miklós Konkoly-Thege in 1874. However, his main target was the Perseids, so when he noticed a few meteors of some unknown origin, he didn’t pay much attention to them. In subsequent decades, sporadic observations of the Kappa Cygnids continued, but their meteors were often attributed to other showers or dismissed as random meteors. Only in the second half of the 20th century did astronomers finally identify the Kappa-Cygnids as a distinct meteor shower.
Kappa Cygnid Meteor Shower 2026: Key Facts
In 2026, the Kappa Cygnids (κ-Cygnids) reach their peak on August 17 under favorable conditions — the waxing Moon will set in the evening and won’t interfere with your observations. Use the Sky Tonight app to determine the best time for observation — when the radiant is high and the Moon has already set. If you live in the Northern Hemisphere, definitely give the Kappa Cygnids a chance this year! And to prepare for a successful meteor hunt, check out our colorful infographic on shooting stars.
What Meteor Shower Comes After the Kappa Cygnids?
The next meteor shower after the Kappa Cygnids is the Aurigids, which peak on the night of August 31–September 1, 2026. This minor Northern Hemisphere shower usually produces up to six meteors per hour and has its radiant in the constellation Auriga.
