Best seen from Northern Hemisphere, with a lower hourly rate in the Southern Hemisphere, Lyrids seem to stream from the Constellation Lyra. They actually derive from the debris trail of Comet C/1861 G1 Thatcher, which has a period of 415 years. Can be “fireball” bright but usually lack persistent trains, they travel ~49km/second and have a maximum rate (ZHR) of 18 per hour.
