The story of Jason and the Argonauts is a tale of heroism, intrigue, betrayal, and tragedy. And it's a story that's told in the stars -- in the fragmented remains of the constellation Argo Navis. Parts of the constellation are visible from the northern hemisphere just above the southern horizon on winter evenings.

áThe night skies of late January and early February are dominated by the constellation of Orion. A constellation is a group of stars in a portion of the sky, usually portraying a mythical figure or an object. In the case of Orion, he is a mighty hunter.
Many constellations are of ancient origin. The early evening skies of winter have many bright stars. Clear and cold winter nights offer spectacular views.
Stars are the most numerous objects seen in the sky. The most obvious difference seen in the stars is their brightness. Some stars stand out while others are just barely visible.

The Quandrantid meteor shower is expected to have a sharp peak around 00:20 UT, on the 4th January. I is recommended that you start observing a few hours beforehand. The predicted rate is 100 ZHR, but a near Full Moon will make the fainter meteors difficult to observe.
With good viewing conditions, however, there is always the large bluish or yellow/green meteors that will shine through.
The radiant is in the constellation Bo÷tes, which now covers the old constellation called Quadrans Muralis.
