The Draconids meteor shower takes place within the boundaries constellation of the Draco. The meteor showers occurs between October 6-10 with the peak occuring on the Oct. 9/10 every year . The Solar Longitude, mistakenly known as Lambda Omicron is 195.4 degrees. This value sometimes expressed as S.L. or λ ☉ 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. This degree is independent of the calender. AMS .
The closest star to the radiant point of the meteor shower is Rastaban. The coordinates can also be determined by the Right Ascension (262) and the Declination (54).
The Zenith Hourly Rate or how many you expect to see during the hour is Var. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 20 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. For this particular meteor shower, bright meteors are more frequent.
