Aquarids

(ak -wă-ridz) Either of two active meteor showers: the Eta Aquarids, radiant: RA 336°, dec 0°, maximize on May 6, having a peak duration of 10 days and a zenithal hourly rate (ZHR) of 45; the Delta Aquarids, double radiant: RA 340°, dec –17° and 0°, maximize on July 28 and Aug. 7, have a peak duration of about 20 days, and a ZHR of about 19 and 10. The Eta Aquarids have an orbit that is closely aligned to that of Halley's comet. They are observed near the descending node of the comet's orbit.

meteor showers whose radiants are located in the Big Dipper. The most important aquarids are the Eta Aquarids (visible every year at the end of April and beginning of May), which are connected with Halley’s Comet, and the Delta Aquarids (visible every year at the end of July and beginning of August).
