Draconids Meteor Shower

When and where does the Draconids Meteor Shower Occur

The Draconids  meteor shower takes place within the boundaries constellation of Draco. The meteor shower occurs between October 6-10 with the peak occurring on the Oct. 9/10 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 195.4 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. This degree is independent of the calender. AMS .

The source of the meteor shower is Comet 21P/Giacobini-Zinner. The coordinates can also be determined by the Right Ascension (262) and the Declination (54).

Zenith Hourly Rate

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.

How to Find and View the Draconids

Northern Hemisphere

You should be able to see the Draconids when it gets dark. The radiant point is located at the head of the dragon. If you located the nearby Ursa Minor and len look a little up and left of the bowl of the constellation, you should be able to find the Draconids. Look in a Northerly direction.

Southern Hemisphere

Those living as far south as Sydney will not be able to see the Draconids. Those living closer to the Equator in the southern hemisphere should be able to see them. Those in Darwin, Northern Australia should be able to see them from about seven to about nine in the evening before they disappear below the horizon.
