The Eta-Lyriden is a weak meteor shower observable from Central Europe . The radiant lies in the eastern area of the constellation Lyra ( Latin Lyra ), about 8 ° northeast of its very bright main star Vega .
The mother body of the Eta-Lyrids is the comet C / 1983 H1 , which passed close to the earth in May 1983 and is also called comet IRAS-Araki-Alcock after its discoverers . In the year of its appearance, meteors of the Eta-Lyrids were observed by several observation groups, with the highest registered ZHR being 5.1 meteors per hour.
Two weeks before the Eta-Lyrids, the much stronger meteor shower of the Lyrids , which has been known since ancient times, appears, whose comet of origin, however, is the C / 1861 G1 (Thatcher) discovered in 1861 .
