The Southern Delta Aquariids meteor shower takes place within the boundaries constellation of the Aquarius. The meteor showers occurs between Jul 12 - Aug 19 with the peak occuring on the Jul 28 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 128 degrees, this value is the the date of maximum activity. It is measured as a degree with zero degree indicating spring equinox (roughly March 21st/22nd). 90 is the Summer Solstice, 180 is the Autumn Equinox and 270 is the Winter Solstice.

The Zenith Hourly Rate or how many you expect to see during the hour is 20. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 41 km/s. The population index of the meteor shower is 3. The population index refers to the magnitude distribution of the meteorites, the smaller the index, the brighter the meteors are, the higher, the dimmer the meteors are.
