The Lyrids are a meteor shower lasting from April 16 to April 26 each year. The radiant of the meteor shower is located in the constellation Lyra, peaking at April 22hence they are also called the Alpha Lyrids or April Lyrids. The source of the meteor shower is particles of dust shed in the cometary tail generated by the periodic Comet C/1861 G1 Thatcher. The Lyrids have been observed for the past 2600 years. The shower on May 22, 687 BC (proleptic Julian calendar) was recorded in Zuo Zhuan, which describes the shower as 'On day xn-mo of month 4 in the summer (of year 7 of King Zhuang of Lu), at night, fixed stars are invisible, at midnight, stars dropped down like rain.' The shower usually peaks on around April 22 and the morning of April 23. Counts typically range from 5 to 20 meteors per hour, averaging around ten. As a result of light pollution, observers in the country will see more, observers in the city fewer.
