Typical Lyrids are about as bright as the stars of the Big Dipper. As meteor showers go, the Lyrids are relatively mild. Most years in April there are no more than 10 to 20 Lyrid meteors per hour. But sometimes, when Earth glides through an unusually dense clump of debris from Comet Thatcher, the rate increases, resulting in what is known as a meteor outburst. Sky watchers in 1982, for instance, counted 90 Lyrids per hour.

So what about this year? The nearly full moon is out around midnight and clouds may spoil some of the show as well. Here's the thing, the Lyrids are active for over a week. While you won't see an abundance of meteors at once, don't be shocked to see a bright, fireball flash across the sky during that time frame.

About the Meteor Shower

The Lyrids, which peak during late April, are one of the oldest known meteor showers: Lyrids have been observed for 2,700 years. (The first recorded sighting of a Lyrid meteor shower goes back to 687 BC by the Chinese.)

The Lyrids are known for their fast and bright meteors, though not as fast or as plentiful as the famous Perseids in August, Lyrids can surprise watchers with as many as 100 meteors seen per hour. Sightings of these heavier showers occurred in 1803 (Virginia), 1922 (Greece), 1945 (Japan), and 1982 (U.S.). In general, 10-20 Lyrid meteors can be seen per hour during their peak.

Lyrids frequently leave glowing dust trains behind them as they streak through the Earth's atmosphere. These trains can be observable for several seconds.


Sky conditions will be good for viewing, but the bright moon may drown out some of the meteors. This shower requires some patience with only up to 10 meteors per hours. Look to the northeast part of the sky after midnight.  

Viewing Tips

The Lyrids are best viewed in the Northern Hemisphere during the dark hours (after moonset and before dawn). Find an area well away from city or street lights. Come prepared with a sleeping bag, blanket or lawn chair. Lie flat on your back with your feet facing east and look up, taking in as much of the sky as possible. After about 30 minutes in the dark, your eyes will adapt and you will begin to see meteors. Be patient -- the show will last until dawn, so you have plenty of time to catch a glimpse.

Where Do Meteors Come From? 

Meteors come from leftover comet particles and bits from broken asteroids. When comets come around the sun, they leave a dusty trail behind them. Every year the Earth passes through these debris trails, which allows the bits to collide with our atmosphere where they disintegrate to create fiery and colorful streaks in the sky.

The Comet

The pieces of space debris that interact with our atmosphere to create the Lyrids originate from comet C/1861 G1 Thatcher. Comet Thatcher was discovered on 5 April 1861 by A. E. Thatcher.

The Radiant

Their radiant -- the point in the sky from which the Lyrids appear to come from -- is the constellation Lyra, the harp. Lyrids appear to particularly radiate out from the star Vega -- Vega is the brightest star within this constellation. (Helpful Hint: Vega is one of the brightest stars in the night sky and is easy to spot in even light-polluted areas.) The constellation of Lyra is also where we get the name for the shower: Lyrids.

It is actually better to view the Lyrids away from their radiant: They will appear longer and more spectacular from this perspective. If you do look directly at the radiant, you will find that the meteors will be short -- this is an effect of perspective called foreshortening.

Note: The constellation for which a meteor shower is named only serves to aid viewers in determining which shower they are viewing on a given night. The constellation is not the source of the meteors.
