The Lyrid meteor shower will reach its maximum rate of activity on 23 April 2019. Some shooting stars associated with the shower are expected to be visible each night from 19 April to 25 April.

Annual meteor showers arise when the Earth passes through streams of debris left behind by comets and asteroids. As pebble-sized pieces of debris collide with the Earth, they burn up at an altitude of around 70 to 100 km, appearing as shooting stars.

By determining the speed and direction at which the meteors impact the Earth, it is possible to work out the path of the stream through the Solar System and identify the body responsible for creating it. The parent body responsible for creating the Lyrid shower is C/1861 G1 (Thatcher).

Observing prospects

The maximum rate of meteors expected to be visible is around 10 per hour (ZHR). However, this assumes a perfectly dark sky and that the radiant of the meteor shower is directly overhead. In practice, the number of meteors you are likely to see is lower than this, and can be calculated from the ZHR formula.

From Washington , the radiant of the shower will appear 20° above your north-eastern horizon at midnight. This means you are likely to see only around 3 meteors per hour, since the radiant will be low in the sky, reducing the chance of seeing meteors.

The radiant of the Lyrid meteor shower is at around right ascension 18h10m, declination 32°N, as shown by the green cross on the planetarium above. All of the meteors will appear to be travelling directly outward from this point, as indicated by the white lines drawn above.

The Moon will be 18 days old at the time of peak activity, and being so close to Full Moon will severely limit the observations that will be possible.

To see the most meteors, the best place to look is not directly at the radiant itself, but at any dark patch of sky which is around 30–40° away from it. It is at a distance of around this distance from the radiant that meteors will show reasonably long trails without being too spread out.
