Theta Centaurids Meteor Shower

When and where does the Theta Centaurids Meteor Shower Occur

The Theta Centaurids  meteor shower takes place within the boundaries constellation of Centaurus. The meteor shower occurs between Feb 12 - Feb 16 with the peak occurring on the Feb 14 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 322.7 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 (210) and the Declination (-40).

Zenith Hourly Rate

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 59 km/s.

Of the meteor Showers located within the boundaries of Centaurus, the Theta-Centaurids are the most northern of all the showers. This doesn't mean that the meteor shower can be seen in the Northern Hemisphere because it doesn't. The other showers are the Alpha/Beta Centaurids and the Omicron Centaurids. The Radiant point of the shower is around Theta-Centaurus also known as Menkent hence the name. The source for the meteor shower is not known as to whether it is a comet or an asteroid breaking up.
