The Alpha Centaurids meteor shower takes place within the boundaries constellation of Centaurus. The meteor shower occurs between Jan 28 - Feb 21 with the peak occurring on the Feb 07 every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 319.4 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 closest star to the radiant point of the meteor shower is Rigil Kentaurus. The coordinates can also be determined by the Right Ascension (212.1) and the Declination (-59.4).
The Zenith Hourly Rate or how many you expect to see during the hour is 5. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 58 km/s. The population index of the meteor shower is 2. 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, faint meteors are more frequent.
The Alpha Centaurids is a southern hemispheric Meteor Shower that is situated within the boundaries of constellation of Centaurus. The Constellation is most famous for having the closest star to our own Solar System, the star in question being Rigil Kentaurus better known to some people as Alpha Centauri.
The Alpha-Centaurids are close to the Beta-Centaurids, whilst the location is similar, the difference is mainly in hourly rate and their magnitude. The betas are more prolific and brighter of the two. Both inhibit the same rough location in the sky and about the same time of the year. The location are estimated where given information what I've seen is where they will radiate from. The radiate points are Rigil Kentaurus for Alpha and Hadar for Beta Centaurids.
Hadar is the lower of the two stars within the yellow circle on the image below. The upper star is Rigil Kentaurus, Alpha Centauri. Alpha Centaurids will appear closer to Rigil and Beta Hadar.
