The source of the meteor shower is 169P/NEAT. The closest star to the radiant point of the meteor shower is Algiedi Prima. The coordinates can also be determined by the Right Ascension (306.5) and the Declination (-9.2).

The Zenith Hourly Rate or how many you expect to see during the hour is 4. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 23 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.
