Epsilon Geminids Meteor Shower

When and where does the Epsilon Geminids Meteor Shower Occur

The Epsilon Geminids  meteor shower takes place within the boundaries constellation of Gemini. The meteor shower occurs between Oct 14 - Oct 27 with the peak occurring on the Oct 18 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 198 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 coordinates can also be determined by the Right Ascension (93.8) and the Declination (28.1).

Zenith Hourly Rate

The Zenith Hourly Rate or how many you expect to see during the hour is 2. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 70 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.

Compared to the Geminids which occur in December, this meteor shower is more low key. It has a low rate of about one or two, not the type of meteor shower you should be looking out for if its cold where you are, there are better showers to look out for such as the "sister" shower in December. The radiant point is situated near Mebsuta, also known as Epsilon Gemini which gives the meteor shower it name. The star is the large spot in the crotch of the nearest twin.

Another meteor shower that is also on at that time is the Orionids in the nearby constellation. If you don't known your Mebsuta from your Rigel, you could end up looking at the wrong one.

How to Find and View the Epsilon Geminids

Northern Hemisphere

Its easier to see the Epsilon Geminids in the northern hemisphere as the constellation will appear early in the evening. The radiant point will appear at about 10pm in a north-easterly direction. The meteor shower should remain visible until morning the next day.

Southern Hemisphere

The Epsilon Geminids will first appear in the sky to the west of Epsilon Geminorum, Over the course of the night, the meteor shower radiant point will move in a seemingly diagonal south direction towards Iota Geminorum where it will then disappear.

The best time to see it is about from after one o'clock in the morning when it will appear on the horizon in a north easterly direction. It will remain visible until sunlight.
