The Lyrids, the first major meteor shower of the year, will be gracing us with fireballs tonight if luck is on our side.
Although this year’s conditions are not ideal due to the peak of the meteor shower coinciding with a full moon, the Lyrid meteor shower still has the potential to produce fireballs, similar to the more famous Perseid meteor shower (mid-July to August).
One of the oldest known meteor showers, with observations dating back over 2,700 years, the Lyrids were first reported by Chinese astronomers who observed the constellation Lyra. The sky experienced significant meteoric activity in 687 BC, 1803, and 1833.
To increase your chances of spotting the Lyrid meteor shower, understand what causes it, and know where to look, this guide provides valuable insights.

When will the Lyrid meteor shower be visible in 2024?
The peak time to witness the Lyrid meteor shower in 2024 is Monday night (April 22-23) in the UK and US regions. However, the nearly full moon on the night of April 23-24 will reduce visibility. Ideal viewing conditions are in the hours before dawn.
The Lyrid meteor shower will be visible from April 14, 2024, extending until April 30, following a yearly recurrence pattern.
Where to look to find Lyrid
The Lyra radiant, where meteors seem to originate, is situated in the Lyra constellation.
During the shower’s peak, the Lyra radiant ascends higher as the night progresses, enhancing the chance of spotting shooting stars and ensuring they don’t disappear beneath the horizon. Look for meteors about two-thirds up in the sky at a 60-degree altitude and a short distance from the radiant. Enhanced visibility can be achieved by including more sky in your field of view.
Lyra is a compact constellation nestled between the Summer Triangle and Hercules constellations, featuring the distinctive star Vega as part of its makeup.
Efficient star hopping techniques can aid in locating Lyra.
- First, identify the summer triangle asterism that includes Vega from the Lyra constellation, Altair from Aquila, and Deneb from Cygnus. This triangle becomes prominent in the April evening sky.
- Spot Vega: As the brightest star in Lyra, Vega acts as a marker for locating the constellation being sought. Its piercing brightness makes Vega easily identifiable.
- Follow the Lyra star pattern: Once Vega is found, identify the parallelogram shape forming the body of Lyra with Vega as one of its corners. Imagination can help visualize the rest of the constellation resembling a small harp or lyre.
If all else fails, using astronomy apps on your phone with a red light filter can be beneficial in identifying celestial objects.
How visible will Lyra be?
The almost full moon during the peak of the Lyrid meteor shower on April 22-23 poses a visibility challenge. Moon glare diminishes the visibility of meteors, stars, planets, and constellations. Dark adaptation of eyes is hindered by excessive moonlight, necessitating around 10-20 minutes for optimal vision adjustment.
Despite the lunar interference, spotting brighter meteors, including fireballs, remains a possibility during this year’s Lyrid meteor shower.
How many meteors can we actually see?
Under optimal conditions with minimal light pollution and close to 18 meteors per hour, meteor visibility varies annually, with an average of 10 to 20 sightings. However, this year’s bright moon will significantly reduce the number of visible meteors to around three to four per hour.
Dr. Darren Baskill, an astrophysicist from the University of Sussex, explains that the Perseid shower in mid-August, without moonlight interference, offers a meteor every five minutes in urban areas and up to one meteor per minute in dark environments.
What causes the Lyrid meteor shower?
Meteor showers occur as Earth crosses paths with debris left behind by comets and asteroids. As this debris orbits the sun, Earth’s orbit intersects, resulting in the combustion of tiny particles in the atmosphere, creating meteoric streaks.
Most meteor-producing particles are as small as grains of sand, but larger fragments can produce fireballs. The “peak” of a meteor shower denotes the densest part of the stream, resulting in higher meteor visibility.
The Lyrid meteor shower is notable for its fast and bright meteors that often leave lasting trails in the sky, aiding visibility against moon interference.
The Lyra comet and mother object of the Lyrids, C/1861 G1 Thatcher, is a long-period comet with a 415.5-year orbit around the sun. With its last perihelion in 1861, it will be a long wait until its return (around 2276).
Lyrid meteor shower: Viewing tips
To improve your chances of viewing the Lyrid meteor shower:
- Reduce light pollution: Choose locations away from bright lights and ensure minimal light obstructs your view.
- Allow night vision adjustment: Let your eyes adapt to darkness, even if moonlight interferes, for better perception of the surroundings.
- Obstruct the moon: Opt for locations where foliage or buildings obscure the moon for clearer views.
- Watch for Meteor Trains: Meteor trains can linger after a meteor, enhancing visibility.
- Use a red light filter: Employ red light filters for devices to maintain night vision.
- Be vigilant for fireballs: Fireballs are rare but possible during the Lyrid meteor shower and are worth watching for.
