The Quadrantids meteor shower takes place within the boundaries constellation of Bootes. The meteor shower occurs between Jan 01 - Jan 05 with the peak occurring on the Jan 03 every year.
The Solar Longitude (Abbrev: S.L., λ ☉) is 283 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 Asteroid 2003 EH1. The closest star to the radiant point of the meteor shower is Nekkar. The coordinates can also be determined by the Right Ascension (230.2) and the Declination (49.5).
The Zenith Hourly Rate or how many you expect to see during the hour is 120. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 41 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 Quadrantids are the first meteor shower to be seen in the solar calendar after making appearance from the very start of the year. Although it has a very high ZHR, they are very faint and are not that spectacular compared to other meteor showers. Whilst some meteor showers such as Geminids are celebrated because their peak intensity can last hours, Quantrantids are brief, they are see very early in the morning and only during a one or hour window. It is also a Northern Hemisphere meteor shower so the more south you are, the less likely you will be to see then.
The reason why the Quadrantids is brief is because the Earth passes through the meteor stream at a perpendicular angle. You'll need to be patient and wrap up warm to see them. Also be well away from any artificial light that might obscure. Before setting out, you should check the weather and what stage the moon is at. If the moon is full then light from the moon will reduce any chance you will have in seeing them. N.A.S.A.
Although they radiant from the constellation of Bootes, they are not named after the constellation. They are named after a now a no longer constellation Quadrans Muralis (Mural Quadrant) which is now consumed into the constellations of Bootes and Draco. The original constellation was created by French astronomer Jerome Lalande in 1795 but was dropped by the International Astronomical Union in 1922 when they agreed upon the current list of 88 constellations. Although the constellation fell out of use, the name for the meteor shower stayed. The Quadrans Muralis included Alkaid.
The source of the meteor shower is believed to be an asteroid much in the same way as the Geminids are. However in this case, the object in question is believed to be asteroid 2003 EH1 which in turn is believed to be related to a comet C/1490 Y1 which was observed hundreds of years ago by Chinese, Japanese and Korean Astronomers.
