The Cygnids are a weak swarm of shooting stars , the meteors of which occur between July 25th and September 8th every year. They seem to come from the constellation Swan (Cygnus) and - in contrast to the well-known Perseids that occur at the same time - cannot be assigned to a known comet, but a planetary meteor shower.
Its very shallow maximum is on August 16th. The radian has approximately the celestial coordinates RA = 13 h 30 ', δ = + 51 °. Two days later is the maximum of a branch of the Cygnid Current, the Cepheids . Its radian is about 15 ° more northwest.
